About This Crate: Colorful Chemistry

  • Did you know? Crayola makes 120 different colors of crayons — all by mixing wax with different pigments.
  • Tree leaves look green most of the time because of the pigment chlorophyll. But they also have red, yellow, and orange pigments hidden underneath. In the fall, the leaves start to lose their chlorophyll. This reveals the hidden pigments for a color-changing show!
  • Early artists made cave paintings using materials they could easily find around them — like red and yellow dirt, white chalk, and black soot from fires.
Colorful pigments can be mixed up into a rainbow of crayons, paints, and more.
