Mostly I edit ruby files, although shell script file comments are also #

Currently my comments show as dark blue on black which is really hard to read.

See screenshot.

How can I change their color?

I'm willing to conside different schemas for all colors though I do like the black background as a base.

I like a contrasting background for comments -- it sets them off from the code, eg. hi Comment ctermbg=gray ctermfg=darkblue. You can set your color scheme and then change it bit by bit; put the bits in a seperate file and source it from your vimrc at the end. –  goldilocks Aug 30 '13 at 16:05
    
:colorscheme evening I love it. It has a dark background. The colors .... well they pierce the darkest of evil :-) –  Bananguin Aug 30 '13 at 19:33

There are many color schemes which are usually distributed together with vim. You can select them with the :color command.

You can see the available color schemes in vim's colors folder, for example in my case:

$ ls /usr/share/vim/vimNN/colors/ # where vimNN is vim version, e.g. vim74
blue.vim  darkblue.vim  default.vim  delek.vim  desert.vim  elflord.vim 
evening.vim  koehler.vim  morning.vim  murphy.vim  pablo.vim  peachpuff.vim
README.txt  ron.vim  shine.vim  slate.vim  torte.vim  zellner.vim

I usually use desert. So I open vim, then enter :color desert and enter.

(Michael, OP) This was good. The terminal looks like:

How could I make that the default without typing that every time? :) –  Michael Durrant Aug 30 '13 at 14:35

Just add the :color desert into your ~/.vimrc so it's executed on startup –  mauro.stettler Aug 30 '13 at 14:36

Welcome, but you should rather accept the answer with the according 'tick' button –  mauro.stettler Aug 30 '13 at 14:46
    
Yes, I will if I think it's the best answer for me but giving a little time to see if there are other alternatives :) –  Michael Durrant Aug 30 '13 at 14:48

You can do it manually with this command:

:hi Comment guifg=#ABCDEF

Where ABCDEF is an appropriate color hex code.

To make it permanent, you will need to add these lines to your ~/.vimrc file (using green as an example):

syntax on
:highlight Comment ctermfg=green

It's also possible to see your current highlight settings with :hi or :highlight (i.e. without any other arguments). –  evilsoup Aug 30 '13 at 16:30
    
@evilsoup thanks. Did you ever try that udev rule I suggested by the way? –  terdon Aug 30 '13 at 16:41

As you are using a dark background in your terminal, you simply need to set

:set background=dark

instead of the default

:set background=light

The colors are then automatically correctly set.

If you want to have this permanently, add the line

set background=dark

to your $HOME/.vimrc file.

One option I found was in terminal preferences (top menu, not the window).

This has profile preferences and then a color tab, e.g.

enter image description here

Changing the Palette entry 5 from Dark blue to Light Lilac helped. I finally chose xterm as the color scheme and lightened up the comment color e.g.enter image description here

My only question now is if whether I can now save those preferences in a file so that they are there for a new machine setup. –  Michael Durrant Aug 30 '13 at 14:43

I use xterm, and set the blue color to something palatable to my eyes in .Xresources: "XTerm*color4: light sky blue". –  holygeek Aug 31 '13 at 15:00
    
+1 It is usually a question of color palette. –  polemon Sep 1 '13 at 8:07
    
+1 holygeek, that basically what I ended up doing. –  Michael Durrant Sep 1 '13 at 12:35

I had precisely this problem a little while ago, the solution is to place the following line in your vimrc file:

set t_Co=256

And then you might have to put the following at the end of your your ~/.profile:

#set vim terminal to 256 colors.
if [ -e /usr/share/terminfo/x/xterm-256color ]; then
    export TERM='xterm-256color'
else
    export TERM='xterm-color'
fi

and then you can set:

hi Comment      ctermfg=lightblue

in your vimrc file and then you will have light blue comments.
vimrc 256: http://vim.wikia.com/wiki/256_colors_in_vim

I also noticed the screen became somewhat prettier by setting it to 256.
