I’ve tried to set color of vim for editing C program text file.

My .vimrc is below.

[.vimrc]

set nu
colorscheme delek
syntax on

And delek.vim file is as follwing list.

ls -la /usr/share/vim/vim72/colors
total 80

$ 

After setting, I re-login and edit C source.

But no words are colored while there is a line under words.

How can I set it?

Check the output of

:set t_Co?

It should print 16 or 256. If not, your terminal isn't properly detected, and you should check your $TERM value. The :highlight command will quickly show you what colors and attributes are available. Also check whether other applications (e.g. mc or htop) can display colors.
