Possible to toggle between two different colorschemes in vim

Question

I have noticed that some files look better than others with different colorschemes. Is there a way to toggle between two different colorschemes, for example:

colorscheme TextMate "OceanicNext

:nmap <leader>C colorscheme Textmate ? colorscheme OceanicNext : OceanicNext

Answer 1

Normally Vim colorschemes set a variable g:colors_name

nnoremap <expr><silent><leader>C printf(':colorscheme %s<CR>',
    \ g:colors_name !=# 'OceanicNext' ? 'OceanicNext' : 'Textmate')
