🎨🎨🎨 Collection of most color palettes in a single R package

paletteer

The goal of paletteer is to be a comprehensive collection of color palettes in R using a common interface. Think of it as the “caret of palettes”.

Notice This version is not backwards compatible with versions <= 0.2.1. Please refer to the end of the readme for breaking changes

Installation

You can install the released version of paletteer from CRAN with:

install.packages("paletteer")

If you want the development version instead then install directly from GitHub:

# install.packages("devtools")
devtools::install_github("EmilHvitfeldt/paletteer")

Palettes

The palettes are divided into 2 groups; discrete and continuous. For discrete palette you have the choice between the fixed width palettes and dynamic palettes. Most common of the two are the fixed width palettes which have a set amount of colors which doesn’t change when the number of colors requested vary like the following palettes:

on the other hand we have the dynamic palettes where the colors of the palette depend on the number of colors you need like the green.pal palette from the cartography package:

Lastly we have the continuous palettes which provides as many colors as you need for a smooth transition of color:

This package includes 2759 palettes from 75 different packages and information about these can be found in the following data.frames: palettes_c_names, palettes_d_names and palettes_dynamic_names. Additionally this github repo showcases all the palettes included in the package and more.

Examples

All the palettes can be accessed from the 3 functions paletteer_c(), paletteer_d() and paletteer_dynamic() using the by using the syntax packagename::palettename.

paletteer_c("scico::berlin", n = 10)
#> <colors>
#> #9EB0FFFF #5AA3DAFF #2D7597FF #194155FF #11181DFF #270C01FF #501802FF #8A3F2AFF #C37469FF #FFACACFF
paletteer_d("nord::frost")
#> <colors>
#> #8FBCBBFF #88C0D0FF #81A1C1FF #5E81ACFF
paletteer_dynamic("cartography::green.pal", 5)
#> <colors>
#> #B8D9A9FF #8DBC80FF #5D9D52FF #287A22FF #17692CFF

All of the functions now also support tab completion to easily access the hundreds of choices

ggplot2 scales

Lastly the package also includes scales for ggplot2 using the same standard interface

library(ggplot2)

ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species)) +
  geom_point() +
  scale_color_paletteer_d("nord::aurora")

Breaking changes

In version <= 0.2.1 a palatte was selected by specifying a package and palette argument like so

paletteer_c(package = "nord", palette = "frost")

After version 0.2.1 palettes are selected using the syntax "packagename::palettename" inside the palette functions.

paletteer_c("nord::frost")

paletteer's Issues

Adding the Harry Potter palette

Maybe this will be worth adding to the next release?
https://github.com/aljrico/harrypotter

Thanks.

bump the development version to `0.2.0.9000`

The CRAN version of paletteer is 0.2.0, while, confusingly, the development version is 0.1.0.9000.

It will be better if you can bump this to 0.2.0.9000. Otherwise I - and any other developer - can't download the development version and run the package tests since the packages will depend on 0.2.0 or above.

ggthemr

Look for palettes in ggthemr
https://github.com/cttobin/ggthemr

Feature request: centered palettes

I was thinking it would be kind of neat to have an option in which colors were assigned from the middle of a palette, rather than from the left (i.e., direction = 1) or right (i.e., direction = -1).

For example say we wanted to use the following palette, but we only had three colors:

paletteer_d(ggthemes, hc_bg)
[1] "#d5e4eb" "#c3d6df" "#ed111a" "#ebebeb" "#c9c9c9"

Normally we'd do something like:

paletteer_d(ggthemes, hc_bg, n = 3) #or possibly paletteer_d(ggthemes, hc_bg, n = 3, direction = -1)
[1] "#d5e4eb" "#c3d6df" "#ed111a"

But what if we wanted to use the middle three colors? Usually I'd do something like:

paletteer_d(ggthemes, hc_bg)[c(2:4)]
[1] "#c3d6df" "#ed111a" "#ebebeb"

That's not terrible, but it can be inconvenient if dealing with a lot of changing group conditions.

What about an even number of groups? Could include an argument for starting from the left or the right of the middle color. Maybe even one for dropping the middle color. This could include similar logic for an even number of colors and an odd number of groups.

Thus, I could see a modification of the paletteer_* functions to include some new arguments:

paletteer_d(..., centered = c(TRUE, FALSE), side = c("left", "right", "middle"))
#Examples of functionality:
paletteer_d(ggthemes, hc_bg, n = 3, centered = TRUE) #original color index: [2, 3, 4]
[1] "#c3d6df" "#ed111a" "#ebebeb"
paletteer_d(ggthemes, hc_bg, n = 4, centered = TRUE, side = "left") #original color index: [1, 2, 3, 4]
[1] "#d5e4eb" "#c3d6df" "#ed111a" "#ebebeb"
paletteer_d(ggthemes, hc_bg, n = 4, centered = TRUE, side = "right") #original color index: [2, 3, 4, 5]
[1] "#c3d6df" "#ed111a" "#ebebeb" "#c9c9c9"
paletteer_d(ggthemes, hc_bg, n = 4, centered = TRUE, side = "middle") #original color index: [1, 2, 4, 5]
[1]  "#d5e4eb" "#c3d6df" "#ebebeb" "#c9c9c9"

Thoughts?

Add palette swatches?

I'd be happy to help with a PR here, but I couldn't figure out an easy way of seeing the palettes from each package. I ended up going with the method used in the ochRe vignette (ochRe exports a viz_palette()) function to make a display of some of them:

But I think the way you do things with pals::pal.bands() in the quickpalette vignette would probably be better for this package (takes up much less space!)

adding games of thrones palettes

https://github.com/aljrico/gameofthrones

How to cite paletteer?

citation("paletteer") refers to an AUTHORS file, but I cannot find it. How else can I cite this package?

feature request: add "vapoRwave"

https://github.com/moldach/vapoRwave

Add National Park palette

https://github.com/katiejolly/nationalparkcolors

Incorrect use of get()

I'm not exactly sure what you're trying to do here:

  objs <- mget(ls("package:paletteer"), inherits = TRUE)
  gen_fun <- get(paste0("paletteer_c_", package), objs)

But I'm pretty sure generating the list of objects first is unnecessary.

Also, I'd suggest using exists() to verify if the palette wrapper is not found so that you can generate a nicer error message.

API documentation for paletteer compatible palettes?

Hey I want to package a few (discrete) colour palettes, and I was wondering if you could provide documentation for generating palette-packages that are easy to integrate with palletteer, maybe as a vignette?

include trekcolors

https://github.com/leonawicz/trekcolors

when using scale_color_paletteer_c(scico, berlin, 20),and have problem?

scale_color_paletteer_c(scico, berlin, 20)+

Error in paletteer_c(package = !!package, palette = !!palette, direction = direction, :
direction must be 1 or -1

I want 20 different colors that are distinct and pretty, how can I choose them ?

include DresdenColor

https://github.com/katiesaund/DresdenColor

Add more examples in general

Add colorspace palettes?

Hi,

I'm wondering if this package may not be included because of the resulting palette redundancy for paletteer, since colorspace borrows palettes from other packages. Or is colorspace worth including? I'm wondering if the focus is more about the palettes or about the collections/packages?

For example, users of paletteer who might be more familiar with colorspace than with other packages might locate a particular palette they are looking for more easily with colorspace in the collection.

If there is interest, I could submit a pull request for the addition.

tidyquant theme

Hi @EmilHvitfeldt,

I'm the creator of the tidyquant package. I have a theme_tq(), palette_light(), palette_green(), palette_dark(), scale_color_tq(), and scale_fill_tq() within the tidyquant package. Would you want to include any of the palettes and/or themes in paletteer?

Here's the link to the tidyquant package: https://github.com/business-science/tidyquant

Thanks, Matt

feature request: adding palettes from `khroma`

https://khroma.archaeo.science/

Feature request: add ggthemr palettes

https://github.com/cttobin/ggthemr

Can't pass object representations of package (or pallete?) names to paletteer_d()

Hi,
Really cool package. I appreciate what you've done here.

I'm running into a bit of trouble passing the names of packages and palettes to paletteer_d(), however.

Here's my scenario: I wanted to create a function for your package that would allow me to visualize the colors from a specific package, palette, etc. so that i could rapidly review the palettes, and see which one might best fit my needs, without having to manually entire each name. Focusing on just the fixed width discrete palettes, I made a function:

library(tidyverse)
library(paletteer)
library(pal)

color_plot_d <- function(package, name, n){
  palette <- paletteer::palettes_d_names %>%
  as_data_frame %>%
  dplyr::filter(package == package, palette == name)
  
  pack <- palette$package
  pal <- palette$palette
  n <- palette$length
  
  pals::pal.bands(
    paletteer_d(pack, pal),
    main = paste(pack, pal, sep = ": ")
  )
}

However, I get this error:

 Error in match.arg(package, unique(paletteer::palettes_d_names$package)) : 
  'arg' should be one of “awtools”, “dichromat”, “dutchmasters”, “ggsci”, “ggpomological”, “ggthemes”, “ghibli”, “grDevices”, “jcolors”, “LaCroixColoR”, “NineteenEightyR”, “nord”, “ochRe”, “palettetown”, “pals”, “Polychrome”, “quickpalette”, “rcartocolor”, “RColorBrewer”, “Redmonder”, “RSkittleBrewer”, “wesanderson”, “yarrr” 

It seems that this behavior is the results of the follwing two lines of code in paletteer_d():

package <- rlang::quo_name(rlang::enquo(package))
palette <- rlang::quo_name(rlang::enquo(palette))

It appears that I can only pass quoted or unquoted versions of the name, but not object representations of the name. I'd hoped to provide a solution to this problem, but this is a level of R I'm not yet familiar with.

Instead, my work around was to simply create a duplicate of the paletteer_d() function, but to comment out the two lines causing me problems. However, this means that if one passes an unquoted representation of a package or palette (e.g. awtools) then a different error occurs.

#The re-worked version of `paletteer_d()`, commenting out the problematic lines.
p_d <- function(package, palette, n, direction = 1, type = c("discrete", 
    "continuous")) {
  if (abs(direction) != 1) {
      stop("direction must be 1 or -1")
  }
  #package <- rlang::quo_name(rlang::enquo(package))
  #palette <- rlang::quo_name(rlang::enquo(palette))
  package <- match.arg(package, unique(paletteer::palettes_d_names$package))
  type <- match.arg(type)
  pal <- paletteer::palettes_d[[c(package, palette)]]
  if (is.null(pal)) 
      stop("Palette not found. Make sure the palette name are spelled correct.")
  if (missing(n)) {
      n <- length(pal)
  }
  if (type == "discrete" && n > length(pal)) {
      stop(paste("Number of requested colors greater than this palette can offer which is ", 
          length(pal), ".", sep = ""))
  }
  out <- switch(type, continuous = (grDevices::colorRampPalette(pal))(n), 
      discrete = pal[1:n])
  if (direction == -1) {
      rev(out)
  }
  else {
      out
  }
}

#The palette generation function I made:
color_plot_d <- function(package, name){
  palette <- paletteer::palettes_d_names %>%
  as_data_frame %>%
  dplyr::filter(package == package, palette == name)
  
  pack <- palette$package
  pal <- palette$palette
  
  pals::pal.bands(
    p_d(pack, pal),
    main = paste(pack, pal, sep = ": ")
  )
}

#These all work:
color_plot_d("awstools", "a_palette")
color_plot_d(paletteer::palettes_d_names$package[1],
  paletteer::palettes_d_names$palette[1])
pack <- paletteer::palettes_d_names$package[1]
pal <- paletteer::palettes_d_names$pal[1]
color_plot_d(pack, pal)

#This does not work:
color_plot_d(awstools, a_palette)

Not sure if this matters to you, but just thought I'd pass the information along, in case it was useful.

Again, I appreciate your effort on this package. Keep up the great work!

I think it's generally bad practice to have an argument that controls whether or not a variable is automatically quoted — and it's definitely not in keeping with tidy evaluation. I'd suggest either eliminating it (and relying on people using !!) or using deparse(substitute(package)) to make it clear that you're not actually using tidyeval.

(If you do want to continue using tidyeval, I'd recommend using ensym() rather than enquo(), since you only want to capture a name, not anything more complex)

Feature Request: Remove NSE options for package and palette.

Hi there! Thanks for writing paletteer, I am currently using it (and prismatic!) in
palap, and I think it’s great, as
it provides an interface to ALL the palettes that I want!

However, recently, I have found that there is an unanticipated
snag I have run into when it comes to using it programmatically, and this
comes from it’s use of bare symbols. I was wondering if you would consider
dropping the behaviour of using bare symbols, instead using characters?

Take this example:

library(paletteer)
paletteer_c(n = 4,
            package = "scico",
            palette = "tofino")
#> [1] "#DED8FF" "#263B65" "#244C27" "#DAE59A"

and then, let’s say that you want to store a few colour palettes, so you
pass them in as objects. This errors, and the error message initially made me
think that perhaps I had a typo.

pkg <- "scico"
pals <- c("tofino", "davos", "lapaz")

paletteer_c(n = 4,
            package = pkg,
            palette = pals[1])
#> Error in match.arg(package, names(wrapper_c)): 'arg' should be one of 
"gameofthrones", "ggthemes", "grDevices", "harrypotter", "oompaBase", "palr",
 "pals", "scico", "viridis"

# But, instead, the workaround in this instance, is this:

library(rlang)
paletteer_c(n = 4,
            package = !!sym(pkg),
            palette = !!sym(pals[1]))
#> [1] "#DED8FF" "#263B65" "#244C27" "#DAE59A"

Which requires understanding a bit more about NSE - not something I would
have predicted, and something that someone new to programming might not
understand, since the error above makes them think that perhaps there
was a spelling mistake, but rather it is a problem to do with passing symbols
This behaviour gets passed onto the user of other packages - say for example
when I used palap, and if the user wants to write their own function
wrapping palap, they have to deal with the same challenge. For example:

library(palap) # remotes::install_github("njtierney/palap")

palap(n = 8,
      palette = "GnBu",
      package = "RColorBrewer")
#> [1] "#F7FCF0" "#C1E6BD" "#5CBCD1" "#0767AC" "#0767AC" "#5CBCD1" "#C1E6BD"
#> [8] "#F7FCF0"


# if you want to wrap this in a function
new_palap <- function(n, palette, package){
  palap(n = n,
        palette = palette,
        package = package)
}

new_palap(n = 6, 
          palette = "GnBu", 
          package = "RColorBrewer")
#> Error in match.arg(package, unique(paletteer::palettes_d_names$package)): 'arg' should be one of "awtools", "dichromat", "dutchmasters", "ggsci",
 "ggpomological", "ggthemes", "ghibli", "grDevices", "jcolors", 
"LaCroixColoR", "NineteenEightyR", "nord", "ochRe", "palettetown", "pals",
 "Polychrome", "quickpalette", "rcartocolor", "RColorBrewer", "Redmonder", 
"RSkittleBrewer", "tidyquant", "wesanderson", "yarrr"

Then they can’t do that - they’ll need to understand some of the features
of NSE.Overall, I think that NSE is a great feature of R, but in this instance, I
actually think it makes it harder to reason and deal with. I spent a bit of
time thinking about this, and I think that maybe it comes down this idea:

Bare symbols should be used to reference something that already exists, or
will exist, and not to denote options (except for boolean TRUE/FALSE)

• For example, an existing column in select(data, barevar),
• Or a new column, such as in mutate(data, newvar = barevar + 1)

In any case, what do you think about changing the API to only use
character strings? I understand that this creates breaking changes, and so might not really be desirable. But this package provides a great interface to so many colour palettes, and I think having them work as character only would mean that it will be easier to program with. I'd be happy to help with a PR to help address this if you like?

Thanks again for creating this package!

supplying arguments through objects not working

Hi.

Love this package so much! I'm trying to implement a call to it in one of my own packages, but am having a bit of a struggle.

Basically, I'm trying to let the user only specify what palette they want to use, find which package it is from, and then call paletteer to output the colours in that palette.

I'm storing the name of the package in an object called pkg, and the palette name in palette.
But when I try to supply these to paletteer, it wont recognise them.

I'm guessing this comes from the symbol coding somewhere, but I am unsure how to work around it.

I've made a list that had all the paletteer's in it, for convenience later:

pals = data.frame(type=c("continuous", "dynamic", "discrete"), stringsAsFactors = F)

pals$palettes = NA
pp = list(paletteer::palettes_c_names,
          paletteer::palettes_dynamic_names %>% rename(palette=name),
          paletteer::palettes_d_names)
for(i in 1:nrow(pals)){
  pals$palettes[[i]] = as.data.frame(pp[i])
}
pals = as_tibble(pals)

The function that finds the supplied palette and its package:

scale3d = function(palette){
  pal_src = paste0("^", palette, "$")
  
 # Find index for palette match
  idx = map(pals$palettes, function(x) grep(pal_src, x$palette))

 # Find index for type match, for call to switch
  type_indx = which(unlist(lapply(idx, function(x) !is_empty(x))))
  
  idx = unlist(idx)
  pkg = pals$palettes[[type_indx]][idx,"package"] 
  
  print(pkg)
  switch(pals$type[type_indx],
         "discrete" = {
           paletteer::paletteer_d(package = pkg,
                                  palette = palette)
         },
         "dynamic" = {
           paletteer::paletteer_dynamic(package = pkg,
                                  palette = palette)
         },
         "continuous" = {
           paletteer::paletteer_c(package = pkg,
                                  palette = palette)
         }
  )
}

include nationalparkcolors

https://github.com/katiejolly/nationalparkcolors

Add argument to darker or lighter output

scale_color_palettes

don't document palette argument

Include meta data about palettes in palettes_*_names objects

would be indicators such as, monochromatic, colorblind resistant, divergent, rainbow, etc etc.

Add FAQ

In reference to #17 & #18

feature request: adding "lisa" package

https://github.com/tyluRp/lisa

Add revised Tol palettes

see https://owi.usgs.gov/blog/tolcolors/

Maybe it is a good idea to add caleblareau/BuenColors

Travis build failing after adding paletteer as a dependency

Hey, thanks for this amazing package! I am importing this package functions in my package. But ever since I added paletteer as a dependency, my Trvis CI build is failing on both Mac OS and Linux (https://travis-ci.org/IndrajeetPatil/ggstatsplot) with the error-

ERROR: dependency ‘oompaBase’ is not available for package ‘paletteer’

I checked the CRAN results for the oompaBase package and everything looks good (https://cran.r-project.org/web/checks/check_results_oompaBase.html), and plus the Travis CI build seems to succeed also for paletteer (https://travis-ci.org/EmilHvitfeldt/paletteer).

So I am wondering if you have any thoughts about why the build might be failing only for ggstatsplot? I wonder if I've misspecified something.

feature request: adding palettes from `basetheme`

It's on CRAN as well
