How to Teach Color Theory to Preschoolers

I worked for many years as a science teacher in Toronto, Ontario, and now am an occasional teacher working on the local school board.

Primary and Secondary Colours Lesson Plan for Preschoolers

I recently visited a friend's kindergarten class, and she and I discussed the joy of discovery inherent in very young children. She told me about this fantastic activity she did with her kids, which sent them over the top in the joy of discovering colour and the magic of mixing pigments. I have three boys who are very active learners even now in their teenage years. Concepts learned at school are learned faster and retained longer when kids actively participate in an activity. Preschoolers excel when presented with an opportunity to physically engage in their learning. The lesson plan outlined below presents a fun, active method of teaching kids primary and secondary colours!

Extensions of the Colour Mixing Activity

The following could be added to the lesson depending upon the time of year the activity is completed:

  • Use smaller paper when making the 'Shaving Cream Paintings' and glue onto cardstock to make Mother's Day or Father's Day cards.
  • If done at Halloween, create more orange and black and have the kids create pumpkins and black cats in the shaving cream for Halloween art.
  • At Christmas time, focus on reds and greens, creating ornaments, presents and Christmas trees in the shaving cream. A Christmas card for the family could be the focus of your 'painting'.

Primary and Secondary Pigment Colours Lesson Plan

Rationale: Colour surrounds all of us. It is important in signs seen and used by all. Stop signs are red and that means stop or danger. Animals use colour as warning signs. Orange and red in snakes usually mean that snake is poisonous. Rainforest frogs use similar colours to warn predators that they are poisonous if eaten. Colours in the home and school can convey moods. Green is a calming colour while the primary colours stimulate the visual sense. Many preschoolers know their primary colours at least before entering school. Most others pick them up quickly in their first few formative months. How do we get all the colours of the rainbow? Active participation will allow the students to see firsthand how various colours are created from the main three primary colours.

Subjects: Science, Art

Grade Level: Preschool; Junior Kindergarten, Senior Kindergarten

Suggested Time: 60 minutes


  • baking sheet or paper plates depending upon whether you want a group focus or individual focus
  • liquid food colouring of the three primary colours: red, yellow, blue
  • shaving cream
  • 81/2 by 11 white printer paper
  • various colour construction paper slightly larger than 81/2 by 11 printer paper
  • baby wipes
  • paper towels for clean-up
  • a paint smock for each child
  • colour wheel for the Art Talk


  1. Students will learn the three primary colours.
  2. Students will learn the three secondary colours.
  3. Students will learn that there are intermediate colours that can be created by mixing primary and secondary colours.
  4. Students will create a 'shaving cream' painting.

Order of Activities:

  1. A few weeks prior to this activity it would be advisable to send a letter home indicating that an activity will be done in class involving the students manipulating shaving cream and food colouring with their hands. Ask for parent volunteers for this activity if it is allowed in your school or preschool. Small group participation with an adult helper would be ideal for this activity.
  2. Art talk using a painting or reproduction of a painting by an artist the class is focussing on in art if possible or at least one that demonstrates use of primary and secondary colours. Vocabulary can be introduced at this time including the three primary colours.
  3. Shaving Cream colour mixing activity. Paint smocks would be advantageous for this activity as it can get messy. Baby wipes will be handy for removing as much colour staining from hands as possible. Alternatively, you could have students use popsicle sticks for colour mixing but the effect will not be as tactile.
  4. Creating their 'Shaving Cream Painting'.

Art Talk: What Are Primary Colors?

Use the information in this capsule in discussing with the children primary colours and colour mixing.

The painting by Marion Baars above this capsule illustrates the primary and secondary colours and how they can be used to advantage in the creation of stunning artwork. The reds and oranges in the picture as well as the blues and greens are related colours because they are found next to each other on the colour wheel. The name of the colour is its hue. The common hues are the colours of the rainbow - red, yellow, orange, green, blue and violet. These hues also make up the primary and secondary colours of pigments. The three primary colours are:

  • red
  • yellow
  • blue

Many colours can be created using these primary colours. Mixing equal amounts of the primary colours result in the secondary colours:

  • orange - red+yellow
  • green - blue+yellow
  • violet - red+blue

If you look again at the picture by Marion Baars, you can see colour variations of the primary and secondary colours. These are made by varying the amounts of the primary colours used or by adding white to 'lighten' a primary or secondary colour. The colour wheel also presented to the right shows the primary, secondary and intermediate colours possible by mixing pigments.

Shaving Cream Colour Mixing Activity

Feel free to modify this activity for large or small groups or individual students by varying what you put the shaving cream on. A plastic-covered table with raised edges could be used for a large group while paper plates could be used for individual exploration. I have designed this lesson plan with groups of four in mind with a parent or older student helper for each group.

  1. Cover a baking sheet with shaving cream.
  2. Tell the students you will be adding a primary colour to a few places in the cream and then wait for the ooh's and ahh's when you do.
  3. Ask the students to identify the colour and then add one more primary colour to a few places in the cream.
  4. After that colour has been identified, ask for a volunteer to mix the two colours together. You may have to demonstrate! Listen again for the ooh's and ahh's when a new colour appears.
  5. Ask the students to identify that colour.
  6. Add a different combination of two primary colours and repeat steps 3 to five. Once all three colour combinations have been created discuss the secondary colours that they have created.
  7. Allow each group to create pictures of colour for a while adding more food colouring to allow each student the opportunity to create secondary and intermediate colours in the shaving cream.
  8. When finished, hands will need to be washed and then wiped with baby wipes to remove as much food colouring as possible.

Shaving Cream Painting

  1. Allow each student, one at a time to lay a piece of the printer paper on top of their final shaving cream creation.
  2. They will probably need assistance patting it somewhat flat on their shaving cream creation. Depending on the size of your baking sheet you may be able to have three students lie their printer paper side by side and do all or most students at once.
  3. Carefully peel the paper off of the shaving cream.
  4. Taking the paper to a sink and using a sharp knife, carefully scrape the shaving cream off of the paper.
  5. The food colouring will have soaked into the paper leaving a mirror image of the students' handiwork.
  6. After it has been allowed to dry help each student choose a complementary colour of construction paper.
  7. With assistance if necessary, have each student glue their painting to the construction paper.
  8. Display the students' handiwork in the classroom or hallway for all to see.

Loved it, too! This is such a fun and easy activity to learn about primary and secondary colors! Both of our girls' favorite center in Kindergarten is shaving cream. It's so easy; will definitely do this in the summer!

cardelean from Michigan on May 16, 2012:

Loved this hub! I had planned on doing some shaving cream activities with my own kids this summer and now I'll be adding a little color. Thanks for the great info!

Teresa Coppens (author) from Ontario, Canada on May 15, 2012:

Glad you liked it! Hope your sister finds it useful.

Sarah Johnson from Charleston, South Carolina on May 15, 2012:

Shaving cream art - how cool! Kids do soak in learning better with hands on activities like this, and it is fun! I will be sending this right over to my sister who teaches preschool. Thanks for sharing.

Teresa Coppens (author) from Ontario, Canada on May 15, 2012:

mwilliams66, thanks for the comment. Feel free to pass on the idea to friends and family with younger children.

mwilliams66 from Left Coast, USA on May 15, 2012:

What a wonderfully enjoyable activity. Very unique. My children are grown now, but I will keep this in my arsenal for my grandchildren (to come).

Teresa Coppens (author) from Ontario, Canada on May 15, 2012:

Thanks Indie. I had great fun putting this one together. I'm hoping to get a video together of the boys later demonstrating this technique. I might do it outside though. I'm sure not all of the shaving cream will stay in the baking sheet!! lol

Teresa Coppens (author) from Ontario, Canada on May 15, 2012:

Thanks HawaiiHeart I had a lot of fun getting my hands in the shaving cream myself! If I had so much fun imagine a group of 3 to 7 year olds!

India Arnold from Northern, California on May 15, 2012:

This has to be the most unique approach to teaching primary and secondary colors I have read. Great idea, and a super fun classroom project for our youngest school age children! What a great hub!


HawaiiHeart from Hawaii on May 15, 2012:

What a fun and interactive way to learn about the colors!
