ELI5: What Is Impressionism?

Impressionism is a way of painting that captures what a quick, real-life moment feels like instead of showing every tiny, perfect detail.

Imagine you are looking out of a moving car window on a sunny afternoon. You cannot see every single leaf on a tree or every pebble on the road. Instead, you see a bright, happy blur of green leaves and golden sunshine. That quick "first look" is called an impression, and that is what Impressionist artists wanted to paint.

Before this style began, artists spent weeks inside dark studios painting things that looked like exact, perfectly smooth photographs. But Impressionists did something new:

• They painted outside: Instead of staying indoors, artists took their paint tubes into the fresh air to paint real things happening right then, like people having a picnic in a park, rain puddles on a busy city street, or boats sailing on a lake.
• They chased the sunlight: Sunlight changes quickly during the day. An apple looks bright red at noon, but it looks deep purple at sunset. Artists painted as fast as they could to catch how the light looked at that exact time.
• They used messy brushstrokes: Up close, an Impressionist painting looks like a bunch of messy, thick dots and dashes of paint. But when you take a few steps backward, your eyes mix all those bright colors together, and the whole picture suddenly looks alive and moving.
