What Makes a Painting 'Modern'?

Imagine you're coloring with crayons, but instead of drawing a pretty picture, you just squiggle the colors wherever they go. That's kind of like modern painting, it doesn't always have to look perfect or realistic. Artists in modern art use big brush strokes, wild colors, and sometimes even strange shapes. It's all about how you feel when you make it, not what it looks like at first glance.
