There are two general types of Turbo Dork paints and one subtype:
Metallics contain pigments and small mica flakes that create a sparkling effect on the paint surface making it look like metal.
Turboshifts are made with tiny glass-like flakes that work like millions of small prisms within the paint. Depending on how the flakes are made, different colors are refracted or reflected in the light. In layman's terms this means that the paint changes color depending on what light you are viewing it under, and what angle you are holding it to that light.
There are three different categories of Turboshifts based pretty much on how they look in the bottle.
True2Color - more or less looks like one of the shifting colors
White Base - looks white with a few flecks of color
Red Base - looks red even though the shifting colors are not red
Zenishifts are Turboshifts that shift differently over different base colors. They appear almost as if they were two metallics in one bottle, with one color or the other dominating depending on what color base they are sitting over. In the bottle they look like one of the colors that they flip between.
