Creating color combinations is a sensibility that most students haven't had a chance to develop. Cutting and combining Color-Aid paper is not the most efficient way to acquire color experience. (Ok, if you don't know about Color-Aid paper then you really are young.) Teaching color theory and relationships is much easier in Illustrator and doesn't have to be a mind-melting experience thanks to the Window>Extensions menu in Illustrator CS4. Your students can choose Kulor and download swatches of color schemes into their swatch collection without actually going to the Kulor website. You can tell your students which swatch collections to work with for each color exercise, for example, or just require them to choose a swatch collection and stick with it. The above color scheme is called "Haiti Relief". If you need to brush up on color theory, visit the kulor.adobe.com links page. There is even a link to Colorstrology where you can find the Pantone color that vibrates with your inner you... or something like that.
