Did you read? Request is *not* to have a terminal colorscheme. Request
is to have a *GUI* colorscheme. Out of terminal one.
CSApprox is creating *terminal* colorcheme out of GUI.
Try the following test:
vim --cmd 'set rtp=~/.vam/CSApprox' -u NORC -i NONE -N
:CSApproxSnapshot /tmp/foo.vim
. What happens now is that /tmp/foo.vim contains colorscheme that starts with …
CSAHi Normal term=NONE cterm=NONE ctermbg=231 ctermfg=16 gui=NONE
guibg=white guifg=black
. Precisely:
… guibg=white …
. &background was dark, terminal background color is black. EPIC FAIL.
This is absolutely not what was requested.
