Random color scheme for vim

.vimrc

function RandomColorScheme()
  let mycolors = split(globpath(&rtp,"**/colors/*.vim"),"\n") 
  exe 'so ' . mycolors[localtime() % len(mycolors)]
  unlet mycolors
endfunction

call RandomColorScheme()

:command NewColor call RandomColorScheme()

To use random color from a list of your favorite colors do this (tested in neovide):

function RandomColorSchemeMyPicks()
    let mypicks = ["pyte", "fokus", "github", "peachpuff", "morning", "simple256", "xcode", "gruvbox"]
    let mypick = mypicks[localtime() % len(mypicks)]
    echom mypick
    execute 'colo' mypick
endfunction

command NewColor call RandomColorSchemeMyPicks()

let s:use_gui = exists('g:neovide') || has('gui_running') || (has('termguicolors') && &termguicolors)
if (s:use_gui)
    call RandomColorSchemeMyPicks()
endif

This takes about 400ms on my machine which is too slow. I optimized this in vegerot/dotfiles@53e6b26 by simply changing "**/colors/*.vim to colors/*.vim
