Mixing Green


In this activity, you will explore painting with yellow and blue and mix a new color—green!

Grade Level

Pre-K, Kindergarten



  • Video


  • Blue and yellow tempera paints in cups
  • Water in a cup
  • Paintbrush
  • Sponge
  • Paper


Let’s look at what you have to paint with today:

  • A paintbrush. It has bristles on one side—these are the little hairs that carry the paint. The other side has a handle to hold the paintbrush.
  • Water to clean the brush
  • A sponge to dry the brush
  • Blue and yellow paint. These are two of the primary colors.
  • Paper to paint on

Do you know why the primary colors are special? We can mix them together to make new colors!

Let’s try mixing two of the primary colors together!

Dip your brush into the yellow paint—not too much, just the tip. Paint some yellow on your paper.

Now, rinse your brush in the water. You can say: “1, 2, 3, stop” as you rinse. Then, dry your brush on the sponge.

Now that your brush is clean, you can add some blue next to the yellow. What happens when they meet? It makes green!

I wonder if you can make a different kind of green. Rinse your brush, then see what happens if you add more yellow to the green. It makes a lighter green!

I wonder how you can make a darker green. Maybe you can add more blue.

You made green. Green is one of the secondary colors!

What do you think will happen if you mix all 3 colors together? Why don’t you try it!


Point to one of the colors on your painting.

How did you mix that color?
