I have the same problem with dark blue.

(Using Windows - not sure if this applies under other OSs.)
Most colours are ultimately defined in vim\vim73\rgb.txt (if
you're using VIM 7.3 of course).
You can simply define your own colour in there and then use
it in your colourscheme or whereever. I add this line
0 96 255 BobBlue
and then use it in my colourscheme:
exe 'hi SpecialKey guifg=BobBlue'
exe 'hi NonText guifg=BobBlue gui=NONE'
if !exists("$TERM")
hi SpecialKey ctermbg=DarkBlue ctermfg=White
hi NonText ctermbg=DarkBlue ctermfg=White
endif
You can define it directly in the colourscheme and avoid the
"exe" complication but then you can't use it in all other places,
as far as I could tell.
Since it doesn't work in DOS terminals I use DarkBlue
background with White text there instead.
You might be able to just edit the DarkBlue colour instead.
You'd have to try that to see. Some core colours
are defined elsewhere though - for example replace all the
colours in rgb.txt with 77 77 77 and gvim still shows the
colours like "red" as usual, although "red" is one of the
lines in the file.
Another problem is that rgb.txt is kept alongside the
executable and so upgrades to the vim version will lose your
changes. You'd expect there to be a way to define your own
colours under $VIMRUNTIME, e.g., include your own rgb.txt
there and have it added to the main colours, but I couldn't
find such a method.
Therefore I have the code below at the start of my _vimrc,
and I keep my BobBlue colour and other colours in the file
$VIMRUNTIME\rgb.txt
It doesn't feel very elegant and there's possibly a better
way to do it - works for me though.
