Candy makers turn sweet treats into a rainbow of colors using dyes. Just like when you're mixing paints in art, it's takes a combination of dyes to create certain colors. Colors get mixed up, but did you know you can separate them again?
In this experiment, water and coffee filter paper will coax a drop of candy dye to separate back into different colors. Brown candies work well. Why? Check the candy wrapper label and you won't see brown dye listed in the ingredients. That's because the candy company uses a variety of colors together to make brown dye.
If you're looking for real color that doesn't come from dye, try fruits and vegetables. The red of a strawberry, the orange of pumpkin, and the blue of blueberries are 100% natural. Ever hear the healthy food advice "Put a rainbow on your plate"? It means eat a rainbow of brightly-colored fruits and veggies.
