Did you know that computer-based color schemes do not correspond to fine art ones? Where you expect green to be a complement color to red, the computer gives you cyan. Why is that? Because computers usually use a HSV color model, while classic painters use a completely different color wheel. And it's available now to Photoshop in the MagicPicker 2.2 color wheel panel. Painters, photographers, designers and everyone else can know use their knowledge of classic arts. They can build their unique color schemes based on intuitive, real-world paint behavior.
