Simpleandfriendly.vim is a project mainly written in Vim Script, it's free.
A simple color scheme - with some eye-friendly colors.

This colors evolved over a long time. I tried to use very eye-friendly colors and put some optical emphasis on comments.

I looked for more subtle colors than those of the VI-distrib. I took a default-scheme and changed around, 'til I liked it. I don't know if the commands are enough for hardcore programmers that work with complex syntax, so feel free to enhance it.
