Color Mixing with Coloring Pages: A Simple Preschool Exploration

How can two colors become a new one? Use a familiar coloring page as a starting point for a short, open-ended color investigation.

Set up the activity

Begin with three crayons or washable paints and a page with a large, simple subject. Ask children to predict what might happen when two colors meet, then let them test their idea on scrap paper before adding marks to the printable. There is no need to teach a fixed result: materials and shades vary, and discovery is the point.

Keep participation flexible

Invite children to name, compare, or invent names for the colors they make. Keep the activity optional, protect the page from wet media if it is an inkjet print, and offer crayons as a low-mess alternative. Ask “What did you notice?” rather than testing for a correct answer.

Choose the pages

Choose a few options from the Numbers collection. Combine the pages you need in the PDF creator.

A 15-minute color investigation

Set out (3 minutes): one printable with broad areas, three washable colors, a scrap sheet, and a small tray. Put out only two colors first so the choice stays manageable. Ask, “What do you think these might look like together?” Record the guess with a quick mark rather than correcting it.

Explore (8 minutes): children make one test mark of each color, then overlap the marks on the scrap sheet. Invite them to compare the result with their prediction. Try changing the order or using a smaller amount of one color. If using paint, keep it on the test sheet until the paper and printer ink have been checked; some home-print inks can run when wet. Crayons, colored pencils, or transparent color overlays are lower-mess alternatives.

Notice and close (4 minutes): ask which attempt they want to keep, name the colors in the child’s own words, and let them add a small amount to the printable if they choose. The adult can write the child’s observation beside the page: “I added a little yellow and it looked lighter.” This makes the experiment visible without suggesting there is one correct mixture.

If a child is not interested in predicting, let them explore first and talk afterward. If the result looks muddy, offer a fresh scrap sheet and smaller marks instead of presenting it as a failure. NAEYC’s color-mixing reflection is useful background for following children’s discoveries rather than forcing a planned result.
