My kids and I had a lot of fun doing this basic color theory activity recently. Before starting the activity, I was unsure how they would react. Although I personally had never discussed with them how primary colors combine to create secondary color, I was wondering whether they might have picked up some of this information along the way from other teachers or books. It turned out that color mixing and color theory was completely new to them though. This made the activity really fun for us all since they were so amazed with the results.

To do this activity, I prepared the following:
- 6 white cups
- Red, yellow, and blue liquid watercolors (we purchased ours from Discount School Supply, but you can also find them on Amazon)
- Plastic pipettes
I placed the six cups in a circle. Going around the circle, I filled one cup with red liquid watercolor, one cup with yellow liquid watercolor, and one cup with blue liquid watercolor. Note that red, yellow, and blue are called “primary” colors. In between each of the three cups with primary colors, I left a blank cup.
When the kids came to the table, I told them we were going to mix the colors together. I asked them to predict what color we would make if we mixed the red and yellow together.
After they made their predictions, I then gave them a plastic pipette to drip some red into the empty cup.
Then they added yellow to the same cup, and were surprised to find that they had made orange! We had our first “secondary” color – a secondary color being one that is created by mixing two primary colors.
Next, they mixed yellow and blue to make green. What a surprise!
Then, they mixed red and blue to make purple. Oohs and aahs all around. 🙂
In the end, we had made a whole rainbow of colors just by using the three primary colors of red, yellow, and blue!
The kids were really curious what would happen if they were to mix all six colors together. So I grabbed another container to let them try it out. We learned that mixing all these colors together makes brown!
Very simple, but also a very fun introduction to color theory for my two preschoolers.

This is a fun, hands-on way to learn about colors! Good idea!
What fun!! We have been playing with colors as well lately. Thank you for sharing at Sharing Saturday!
Excellent explanation written in an easy way to understand/explain for kids! My daughter is almost 4 and we just recently did a food coloring and water experiment with her blender. I didn’t get into much detail with her but your explanation is perfect, thanks for a great post!
This is terrific! I love how hands on it is and you explained it very well!
Thank you for stopping by the Thoughtful Spot Weekly Blog Hop this week. We hope to see you drop by our neck of the woods next week!
I don’t think I’ve ever sat my kids down to see if they know color theory either, but they sure would love this activity (sorry I’m so late commenting, got behind).
Thanks for linking up to Science Sunday!
