WHAT GIVES FRUITS AND VEGETABLES THEIR COLORS?
Fruits and vegetables get their colors from different compounds. The three types of pigments that give fruits and vegetables their colors are carotenoids, flavonoids, and chlorophyll.
- Carotenoids – this pigment causes orange, red, and yellow colors. Carotenoids are antioxidants meaning they help protect the cells in our body against damage.
- Flavonoids – this pigment is responsible for yellow, purple, blue, and red colors. Anthocyanins are a type of flavonoid and are responsible for the color in red cabbages among many other fruits and vegetables.. Anthocyanins produce different colors that range from red to purple to blue/green depending on the pH level. This is why the dye produced from red cabbage changes color when you add baking soda (which is basic).
- Chlorophyll – this pigment is responsible for green colors. Chlorophyll helps plants capture energy from the sun so they can grow.
Many of these pigments also have significant health benefits. That is why it is important to eat a balanced diet! Click the button to the right to learn more about plant pigments.

MAKE ICE CUBE ART
Add the natural dyes to an ice cube tray with cornstarch and baking soda, then pop in the freezer. When frozen, use the cubes to draw outside on the sidewalk on a summer day. As the ice cubes melt, you’ll have watercolor artwork.
You can find a set of instructions below, or watch the video to learn more about the fabric dying process.
