Mixing yellow and blue paint to create green paint is which type of change?

Explanation:
Mixing yellow and blue paint to make green is a physical change. You’re simply blending two substances without forming any new chemical bonds or compounds. The pigments keep their identities, and the green appearance comes from subtractive color mixing—the way the two pigments reflect and absorb light together. There’s no chemical reaction, so no new substance is produced. If you could separate the pigments again, you’d restore the original colors, which is characteristic of physical changes.
