what is a "color stable dye" window tint?

A color stable dye window film is a multi ply window film. They will use dyes to get the charcoal look you see on all factory suv’s with smoked glass. The dye product will offer a small amount of heat rejection but because it is designed for looks it matches great to the back part of truck and suv’s with the smoked out glass. The color stable dye offers 99% UV protection and is the choice film for all dealerships.
