Iterating over a ColorScheme creates unexpected results about colorschemes.jl

[lhupe]

If you decide not to, it would be nice to disable the broken iteration behaviour altogether (i.e. overwriting iterate with something that throws an error), so users don't get tricked by the fact that all the functions appear to work (unless you actually take a look at the output, that is…)

[lhupe]

For the record: this

julia> [c for c ∈ ColorSchemes.Dark2_3[1:3]]
3-element Array{RGB{Float64},1} with eltype ColorTypes.RGB{Float64}:
 RGB{Float64}(0.106,0.62,0.467)
 RGB{Float64}(0.851,0.373,0.008)
 RGB{Float64}(0.459,0.439,0.702)

works fine

Hi! Yes, I don't think there's an iterable interface to a colorscheme. You'd probably do:

[c for c ∈ ColorSchemes.Dark2_3.colors]

to run over the colors...

I don't know whether to add an iterable interface...

Hopefully fixed in ece0ffe
