Generate color combination from one color

I need to generate a color combination (monochromatic, triad, analogous, split, etc) from one color in Java. Just like they do in kuler, o开发者_如何学Gonly I want to present it in a JSP page). How can I get the RGB value of the colors in the color combination? Is there a formula or API to do this?

I don't know what all those terms mean, but you might find that using HSL Color values may make it easier to find related colors.
