What Makes a ‘Good’ Paint and Why Do Colors Change Over Time?

A good paint is like a strong, happy friend. It stays bright and doesn’t get sad or tired over time. But sometimes paints change color because they are made of things that react to light and air. Like how your skin gets tan from the sun, paint can also be affected by light and time.

Some paints use special ingredients called pigments, which are like tiny color dots. If those pigments get tired or start talking to other colors, they might change shades over time. For example, a red apple might become more orange if it stays in the sun too long.
