Okay, bookmark this link because you're going to learn to truly love it. http://www.colorpicker.com/
With that site you can pick a color you like. In the top, you'll see # with an alpha/numeric six digit code. For example #FFFFFF is white and #000000 is black.
In the various parts of the Simple CSS Lite plugin, you simply copy the code and insert the # first. So, if you wanted a deep red background color for menu items, you'd add #C00000 and thinking in terms of contrast, you'd probably want a white link. Since you might like to mouseover, it should still be light, so try a pale yellow, again, finding the right shades and colors you prefer using the colorpicker website. Go to the full post
