Changing Vim Colours

[MrNewbie]

I looked in the c.vim syntax highlighting file to see if I could change the colour that various parts of the code appear in but I can't see a colour listed for each part, what do I need to edit to change the colours the syntax highlighting displays?

Look on your system for 'synload.vim'

Thanks a lot.
