I am new in web-design. I know that color plays an important in web design. I have learnt from "The Principles of Beatufiul Web Design (Jason Beaird)" that using www.colorschemedesigner.com is a good place for deciding on colors.

But in that site, the site produces a total of 12 colors on my chosen scheme. But I saw no site using 12 colors as color palette. I don't to how to choose colors. I always have to scratch my head to choose harmonious color palette

Can you give me suggestions on how to choose color palette (especially from the 12 colors produced by colorschemedesigner).
