Why Do Paintings Look Glossy or Matte?

Paint has two main parts: color and glue. The glue part is called binder. When you mix more glue into the paint, it dries smoother and shinier like a polished apple. Less glue means the surface stays rougher, making it look dull like chalk.

Artists choose how much shine they want for different reasons. A shiny painting catches your eye and makes colors pop. A matte painting looks soft and calm. Imagine looking at a wet sidewalk versus a dry one. The wet road reflects the sky; that is gloss! Artists add special powders to stop the shine if they want it gone.

Over time, dust and grime settle on paintings. If a painting gets too dirty, conservators wash it. But washing can change how shiny it looks! That is why knowing about paint gloss helps experts keep art looking new.
