Inspired by (or rather, straight-up copied from) the excellent base16 framework, this Vim plugin makes it easy to create decent looking Vim colorschemes using a palette of 16 xterm-256color codes. To create a cterm16 colorscheme, set the value of the 16 color variables, and then call CTerm16Apply with your colorscheme name. For example, the cterm16-lucid colorscheme is defined using:
let g:ct16_0 = 234 " primary background
let g:ct16_1 = 238 " secondary background (status bars, line number, fold marks)
let g:ct16_2 = 237 " selection background
let g:ct16_3 = 245 " comments, invisibles, line highlights
let g:ct16_4 = 254 " secondary foreground (status bars)
let g:ct16_5 = 253 " primary foreground, caret, delimiters, operators
let g:ct16_6 = 254 " tertiary foreground (rarely used)
let g:ct16_7 = 234 " tertiary background (rarely used)
let g:ct16_8 = 167 " variables, markup lists, diff deleted
let g:ct16_9 = 116 " integers, booleans, constants
let g:ct16_A = 110 " classes, markup bold, search background
let g:ct16_B = 150 " strings, inherited class, diff inserted
let g:ct16_C = 181 " support, regex, escape characters, markup quotes
let g:ct16_D = 216 " functions, methods, headings
let g:ct16_E = 110 " keywords, selector, markup italic, diff changed
let g:ct16_F = 181 " deprecated, embedding language tags
call CTerm16Apply("lucid")
If you'd like to customize how the color palette is applied, you can add something like this to your vimrc:
augroup custom_colorscheme
autocmd!
autocmd ColorScheme * call CTerm16Highlight("MatchParen", "", g:ct16_5, "")
augroup END
In case you're wondering why you'd use this instead of base16 itself, here are the differences:
- Only sets cterm attributes. Doesn't bother with gui attributes.
- Uses xterm-256color codes. Doesn't override your shell's system colors.
- Just a Vim colorscheme. Doesn't do anything else.
Who are we kidding? You don't care about the how, you just want to know if the included colorschemes are any good. Judge for yourself:
