Tip: With simply a third line you can create a cool flip-flop paint. Simply add a Curve, input: Angle, output: Color. The color depends on the viewing angle. This special paint is sometimes used eg on pimped cars. But with the curve object you can simply create an advanced flip-flop paint with 3 or more colors. Simply play with the 3 color curves!
