There are two ways to create Kuler color themes on the iPhone: using the color wheel, and using the camera. The color wheel is exactly the same as the redesigned color wheel on Kuler’s website — you drag small circles around the wheel to create millions of color themes. You also have the standard rules at your disposal (analogous, monochromatic, triad, complementary, etc.) to generate a multi-color palette using your chosen color as a starting point. You also have the ability to change hex values for one or all of the colors in your theme.
