If you are looking forward for a color scheme for your website, Color Scheme designer is another good place to start with. It allows you to generate color schemes
It allows you to create different colour scheeme with help of a rotator to adjust between combination of Red Green and Blue and then choose different options like mono, compliment, traid, tetrad, analogic and accented analogic to create combination which a normal user will tkae ages to think about.
After this you can get a preview of how this combination will look line when applied on a website. The preview is genrated keeping in mind on how many sections your website can have which could be from 2 column to 4 column themes. You can also choose between a dark and a ligh version of the scheme to see the difference.
