Why Do Van Gogh's Paintings Look So Thick?

When you look at a Van Gogh painting, the colors almost pop off the canvas like little hills. This is because artists use a lot of thick paint instead of spreading it thin like butter on toast.

Imagine squeezing toothpaste straight from the tube onto your brush. That lump stays there! In paintings, these lumps are called impasto. They catch the light in different ways depending on where the lamp is in the room.

This technique makes the painting feel alive. If you touched it, it would be bumpy and rough. Artists do this to show how much energy they had when they painted. Instead of hiding their brush marks, they let them shine out for everyone to see.
