Why Do Some Paintings Look Shiny While Others Look Matte?

Imagine you are eating an apple. If the apple is wet from rain, it shines brightly because light bounces straight off the smooth surface. This is called gloss. If the apple is dry and fuzzy, the light gets scattered in all directions, so it looks dull or matte.

Paint works the same way! Paint has two main parts: colored dust (pigment) and a sticky glue-like substance (binder). When artists mix their paint, they can change how shiny it will be. If they add more of that sticky glue, the dried paint becomes smoother like ice. Light hits it and bounces back sharply, making it look glossy.

Sometimes, the shine comes from what is on top. Just like you might put wax on your car to make it pop, artists apply a clear coating called varnish over their finished paintings. This varnish acts like a glass shield, adding extra shine and protecting the colors underneath.

So, whether a painting looks shiny or dull depends on its ingredients and how much light hits its surface. A high-gloss painting feels vibrant and new, while a matte one feels soft and velvety.
