I mean really, who came up with this as a flavor when we were kids? They should get a medal.
Blue Raspberry appears white in the bottle but develops into a blue front facing color that quickly transitions to a raspberry/magenta when used over a black undercoat. I would say this is one of our most "active" paints and really shows off the shift effect in almost any lighting situation.
Turboshift paints 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.
Formulated for airbrush use, but may also be hand brushed.
