Light dye is a type of dye that is used to change the color of fabrics and other materials. It is a permanent dye that is applied to the material and then exposed to light, which causes the dye to become activated and bond with the material. TINT is a term used to describe a lighter shade of a color, usually achieved by adding white to the original color. Light dye is often used to create tints, as it can be used to lighten the color of a fabric or material without changing its hue.
