" To install, copy to ~/.vim/colors directory. Then :colorscheme spectro
|
||||
|
||||
" spectro is a colorscheme that lets you define the global saturation and
|
||||
" the global lightness to be used for all the colors. The hue is then
|
||||
" defined on a per color basis
|
||||
" hue, saturation and lightness shall be set between 0 and 255
|
||||
" I shamelessly used inkscape colors algorithm for HSL -> RGB conversion
|
||||
|
||||
" The main interest is the ability to adapt to different screens
|
||||
" by only changing the saturation and lightness in your vimrc :
|
||||
" let g:spectro_saturation = 120
|
||||
" let g:spectro_lightness = 160
|
