I think you mean hexidecimal codes that represent colors... Those you can find in programs like Adobe Photoshop... But I'll give you a list of sites that have the colors, along with the hexidecimal codes that you'll need to input in admin>edit forum colors...
And some of those sites will tell you how to put variants on the codes that they give you to get different hues on the color you want... Hope that that was helpful...
