How are colors formed?



Experiment: Breaking down color


Hypotheses: Ask children how colors are formed. Are certain colors combinations of other colors? Which ones? Some colors do not come from a combination of other colors, which ones?



  • Coffee filters
  • Markers, variety of colors
  • A glass of water


  1. Using markers, draw circles of different colors on a coffee filter. Be sure to space them out. Use several coffee filters as needed.

  2. Wet your finger by dipping it in the glass of water and place it over each of the coloured circles, letting a few drops of water fall onto each circle.

  3. Observe what happens.

  4. Wait a few minutes and you will see the different colors appear once the coffee filter is dry.

Explanation: Most colors are formed by mixing 3 simple colors called primary colors. Primary colors are red, yellow, and blue. By combining these colors, we get secondary colors.


Primary + Primary = Secondary


Blue + Yellow = Green


Blue + Red = Purple


Yellow + Red = Orange

If you combine primary and secondary colors, you can create an infinite number of colors!


In our experiment, the water separated the colors on the filter paper. How many different colors can you observe?
