The Impact of Light on Dyes and Stains
Preserve intended hues by learning what light does to coloring agents
Whatever dye or pigment stain you use, it will fade or change color with exposure to bright light. The solution is not to swear you’ll never stain wood again (after all, natural colors in wood are affected by light too), but rather to learn which coloring agents to use, how to use them, and what else you can do to preserve the intended color. In this article, Teri Masachi discusses the lightfast properties of pigments and dyes, what happens when they are mixed, and the ultraviolet protection offered by some clear coats.
