hmmm...i am a little rusty.
here is my personal blog and it seems to be doing what you would like.
here is the code where you control the colors:

the "value" at the end is your color. there are tables somewhere online that you can scroll over a color and then they will give you the value. I can help later (like tonight) if you need further help.
