Here we see a triad colour combination of the secondary colours—purple, green and orange—in the Jugo Juice logo. This is a vibrant triad, and I think it’s a good colour scheme for a juice company—the secondary colours really call to mind healthy fruits and vegetables: plums, grapes, carrots, lettuce, spinach, eggplant, beets, etc . . .

Aside from berries, primary colours don’t really suggest natural foods in this manner. While you can find primary colour triad schemes all over the place, this one seemed pretty rare to me . . . until I spotted it used three times within one week!
