My theme, Choices will soon have version two released with a theme builder inside of the wp administration panel for you to chnage the colors, and font of your blog without any CSS knowlage! All that you have to do is take the numbers associated with the color that you want and put them in the text box!
The current release is version one which does not have the theme builder, however it does have HEAVILY commented files throughout the theme. Just about every other line in all of the files assiciated with the theme. With just a small amount of CSS knowlage you can change anything that you want!
