Options

Some options of the original solarized theme were removed or renamed to avoid config conflicts. Make sure to put configuration before the line colorscheme NeoSolarized in init.vim or .vimrc.

" default value is "normal", Setting this option to "high" or "low" does use the 
" same Solarized palette but simply shifts some values up or down in order to 
" expand or compress the tonal range displayed.
let g:neosolarized_contrast = "normal"

" Special characters such as trailing whitespace, tabs, newlines, when displayed 
" using ":set list" can be set to one of three levels depending on your needs. 
" Default value is "normal". Provide "high" and "low" options.
let g:neosolarized_visibility = "normal"

" I make vertSplitBar a transparent background color. If you like the origin solarized vertSplitBar
" style more, set this value to 0.
let g:neosolarized_vertSplitBgTrans = 1

" If you wish to enable/disable NeoSolarized from displaying bold, underlined or italicized 
" typefaces, simply assign 1 or 0 to the appropriate variable. Default values:  
let g:neosolarized_bold = 1
let g:neosolarized_underline = 1
let g:neosolarized_italic = 0

Truecolor test

You can run this script to test if your terminal is supported. If the colors blend smoothly like: , then you know that you have True Color support.

awk 'BEGIN{
    s="/\\/\\/\\/\\/\\"; s=s s s s s s s s;
    for (colnum = 0; colnum<77; colnum++) {
        r = 255-(colnum*255/76);
        g = (colnum*510/76);
        b = (colnum*255/76);
        if (g>255) g = 510-g;
        printf "\033[48;2;%d;%d;%dm", r,g,b;
        printf "\033[38;2;%d;%d;%dm", 255-r,255-g,255-b;
        printf "%s\033[0m", substr(s,colnum+1,1);
    }
    printf "\n";
}'

Tmux

You may need the same hack to make vim work well in tmux. Put these lines into your .vimrc:

set t_8f=^[[38;2;%lu;%lu;%lum
set t_8b=^[[48;2;%lu;%lu;%lum

The '^[' represent the escape char. You should press Ctrl-v + Esc to input actual escape. If the ^[ is two characters (^ and [), it's wrong. If it is one character, it's okay. When you delete the character with backspace, you will find that ^[ is deleted at once. Please also check :help c_CTRL-V (and :help i_CTRL-V). check issue and issue for more information.

neovim works perfect without this config. If you encounter a color issue using tmux, make sure that:

• you are using the latest version of tmux (v2.2)

• your $TERM variable is set to "xterm-256color"

• add the line below to your .tmux.conf file:

  set-option -ga terminal-overrides ",xterm-256color:Tc"

See this article for more details on tmux.
