Re: colorscheme 16-bit

The problem is that too many colorschemes these days are not
cterm-conscious: they assume that you have a lot of colours at your
disposal and sometimes even that you are using gvim — and yet, Vim, as
an editor, is still extremely useful for some tasks that have to be
done with no GUI interface; one of these tasks would be rescuing a
failed software upgrade, where you can't rely on a functioning X11
server: then you are left with the "bare bones" console which usually
has only 8 background and 16 foreground colors, and uses the cterm=
ctermbg= ctermfg= settings of the :hi command, not the gui= guibg=
guifg= guisp= settings. Another such task would be tweaking settings
on a server where no X11 package is installed (and usually no screen
or keyboard either but the sysadmin added them for the occasion).

IMHO Vim's default colors are quite good, though not perfect (nothing
is perfect) for both cterm and gui (I haven't had the occasion to test
the term= colors for lack of the necessary monochrome-terminal
hardware in the days since I've known Vim) so I use an owncoded
colorscheme which defines only what I regard as insufficient in the
default colors (and no shame on Bram: de coloribus non est
disputandum). When running Console Vim in a terminal which is capable
of 256 colors (such as konsole or xterm) I supplement this colorscheme
(which you'll find attached; feel free to use it or not, and if you
do, to adapt it to your own use case; if you want to try it, its home
is in ~/.vim/colors on a Unix-like system, or in ~/vimfiles/colors on
a Windows system) with the CSApprox plugin (available at vim.org), so
in that case I get the same colors, or as close as possible and almost
indistinguishable to my eye, in Vim in konsole or xterm and in gvim.
(I wrote that colorscheme before the 'termguicolors' option was
available and this way I don't depend on the +termguicolors feature
being compiled-in.) Of course, in the 8/16 bare-bones console (where
CSApprox detects that &t_Co < 88 and disables itself) the colors are
very different but at least they are distinct.

Best regards,
Tony.
