Lesson Overview
Age: 14
Suggested time: 75–90 minutes, or two 45-minute sessions
Topic: Traditional pigment color mixing using the red-yellow-blue system
Real-world connection: Artists, designers, painters, illustrators, and printers study how a limited set of pigments can create many useful colors.
Learning Objectives
By the end of the lesson, the learner will be able to:
- Identify red, yellow, and blue as the traditional pigment primary colors.
- Explain why primary pigments are treated as starting colors in the traditional RYB color system.
- Create orange, green, and violet by combining equal parts of two primary pigments.
- Create six tertiary colors by mixing equal parts of a primary color and its neighboring secondary color.
- Arrange colors in a logical color wheel and describe relationships such as primary, secondary, and tertiary.
- Record observations about color mixtures and explain why actual paint results may differ from expected results.
Key Vocabulary
- Pigment: A substance that gives paint, ink, or another material its color by absorbing some wavelengths of light.
- Primary color: A starting color in a particular color system. In the traditional pigment system, these are red, yellow, and blue.
- Secondary color: A color made by mixing two primary colors in equal parts.
- Tertiary color: A color made by mixing one primary color with a neighboring secondary color in equal parts.
- Hue: The basic color name, such as red, green, or violet.
- Equal parts: The same amount of each paint, such as one brushload of red and one brushload of yellow.
Success Criteria
The learner is successful when they can:
- Correctly label red, yellow, and blue as the traditional primary pigments.
- Mix three recognizable secondary colors using equal amounts.
- Mix and label six tertiary colors correctly.
- Place all twelve colors in an orderly color wheel.
- Use consistent measuring and explain at least one reason a mixture may look different from another artist’s mixture.
Introduction: Hook and Objectives — 10 Minutes
Hook: “Can Three Colors Make Twelve?”
Show the learner the three primary paints: red, yellow, and blue. Ask:
- “How many different colors do you think we can make from these three paints?”
- “Can a painter create a wide range of colors without owning every color of paint?”
- “What might happen if we mix exactly the same amount of two colors?”
Invite the learner to make a quick prediction. They may write, sketch, or explain their idea aloud.
Share the Learning Target
Explain:
“Today you will use the traditional red-yellow-blue pigment system to build a twelve-part color wheel. You will first identify the three primary colors, then create secondary colors and tertiary colors by using equal parts.”
Body: Explore and Practice
Part 1: Establish the Primary Colors — I Do — 10 Minutes
Display or place three paint samples on paper. Label them:
- Red
- Yellow
- Blue
Explain that the traditional pigment system begins with red, yellow, and blue. These colors are treated as primary because the system uses them as the basic starting points for mixing other hues.
Model how to make a clean paint sample:
- Use a clean brush or measuring tool for each color.
- Place a small, controlled amount of paint on the palette.
- Spread the color into a neat swatch.
- Write the color name beside or below it.
Teacher or homeschool guide demonstration: Place one equal-sized sample of red, yellow, and blue in three separate sections of the palette. Point out that equal parts must be measured as consistently as possible.
Quick Check
Ask the learner:
- “Which three colors are the traditional pigment primaries?”
- “Why should we use clean tools when mixing?”
- “What does equal parts mean in this activity?”
Part 2: Create the Secondary Colors — We Do — 15 Minutes
Explain that secondary colors are made by mixing two primary colors in equal parts.
| Mixture | Secondary Color |
|---|---|
| Equal parts red + yellow | Orange |
| Equal parts yellow + blue | Green |
| Equal parts blue + red | Violet or purple |
Model the first mixture, red plus yellow:
- Measure one equal part of red.
- Measure one equal part of yellow.
- Mix slowly until the color is mostly uniform.
- Paint a swatch and label it “orange.”
- Record whether the orange appears more reddish, more yellowish, or balanced.
Have the learner help complete the green and violet mixtures. Encourage them to compare the results with their predictions.
Think-Pair-Share or Discussion
If working with a group, learners discuss their results with a partner. If working independently, the learner can write a short response:
“Which secondary color was easiest to make? Which one was hardest to control, and why?”
Formative Assessment
Ask the learner to cover the labels and identify each secondary color by looking at the paint samples. Then ask them to explain the recipe for each color.
Part 3: Build Tertiary Colors — I Do, We Do, You Do — 25 Minutes
Explain that tertiary colors are made by mixing a primary color with a neighboring secondary color. The two colors should be close together on the color wheel.
| Equal-Part Mixture | Tertiary Color |
|---|---|
| Red + orange | Red-orange |
| Yellow + orange | Yellow-orange |
| Yellow + green | Yellow-green |
| Blue + green | Blue-green |
| Blue + violet | Blue-violet |
| Red + violet | Red-violet |
I Do: Model One Tertiary Mixture
Demonstrate red-orange:
- Place one equal part of red on the palette.
- Place one equal part of orange beside it.
- Mix the two parts thoroughly.
- Paint a swatch and label it “red-orange.”
- Compare it with the original red and orange samples.
We Do: Complete One Mixture Together
Make yellow-orange together. Ask the learner:
- “Which primary and secondary colors are we combining?”
- “How can we make sure the parts are equal?”
- “Where should this color go on the color wheel?”
You Do: Complete the Remaining Tertiary Colors
The learner independently creates yellow-green, blue-green, blue-violet, and red-violet. They should use a fresh section of the palette for each mixture and record the recipe beneath each swatch.
Suggested observation chart:
| Color | Recipe | What I Notice |
|---|---|---|
| Red-orange | 1 part red + 1 part orange | |
| Yellow-orange | 1 part yellow + 1 part orange | |
| Yellow-green | 1 part yellow + 1 part green | |
| Blue-green | 1 part blue + 1 part green | |
| Blue-violet | 1 part blue + 1 part violet | |
| Red-violet | 1 part red + 1 part violet |
Part 4: Arrange the Twelve-Part Color Wheel — You Do — 15 Minutes
Have the learner draw a large circle and divide it into twelve sections. They may use a ruler and compass, fold paper to create guidelines, or use a prepared template.
Arrange the colors in this order:
- Red
- Red-orange
- Orange
- Yellow-orange
- Yellow
- Yellow-green
- Green
- Blue-green
- Blue
- Blue-violet
- Violet
- Red-violet
The learner may paint the wheel, use colored pencils, or create a digital version. Encourage neat labels and consistent samples.
Choice and Creativity Challenge
Choose one option:
- Nature study: Find objects in nature that resemble three of the colors on the wheel.
- Design study: Create a small poster using only three neighboring colors.
- Digital investigation: Re-create the color wheel in a digital drawing program and compare it with the painted version.
- Artist’s palette: Design a color palette for a sunset, forest, underwater scene, or imaginary planet using at least one primary, one secondary, and two tertiary colors.
Formative Assessment Throughout the Lesson
- Ask the learner to predict the result before each mixture.
- Check whether equal parts are being measured consistently.
- Ask the learner to identify color recipes without looking at notes.
- Have the learner point to neighboring colors on the color wheel.
- Pause for a “show me” check: “Show me the mixture that creates green,” or “Show me where blue-violet belongs.”
Summative Assessment: Color Wheel Demonstration
The learner submits or presents:
- A labeled twelve-part color wheel.
- Three primary color samples.
- Three secondary color samples with recipes.
- Six tertiary color samples with recipes.
- A short written or spoken explanation of how equal-part mixing was used.
Simple Rubric
| Criteria | Excellent | Developing |
|---|---|---|
| Color identification | All primary, secondary, and tertiary colors are correctly identified. | Some colors or labels need correction. |
| Mixing process | Equal parts are measured carefully and mixtures are reasonably consistent. | Measurements are uneven or mixtures are incomplete. |
| Color wheel arrangement | All twelve colors are placed in logical sequence. | Several colors are out of sequence or missing. |
| Explanation | The learner clearly explains primary, secondary, tertiary, and equal-part mixing. | The explanation is incomplete or uses terms inaccurately. |
| Observation and creativity | The learner records thoughtful observations or applies the colors in an original design. | Observations or creative application are brief or unfinished. |
Differentiation and Adaptations
Support for Learners Who Need More Scaffolding
- Provide a pre-divided twelve-section color-wheel template.
- Use measuring spoons or droppers with clearly marked amounts.
- Complete one mixture at a time instead of preparing all colors at once.
- Provide sentence starters such as, “I mixed ___ and ___ to make ___.”
- Use color-name cards that the learner can physically place beside each swatch.
- Allow oral explanations instead of requiring a written paragraph.
Extensions for Advanced Learners
- Investigate how changing the ratio affects the hue, such as two parts yellow to one part red.
- Compare two different red, yellow, or blue pigments and explain how they affect the mixtures.
- Research the difference between the traditional RYB system and the modern light-based RGB system.
- Create a value scale by mixing one chosen hue with increasing amounts of white or black.
- Design a painting using only neighboring colors from the completed color wheel.
Flexible Learning Formats
- Homeschool: Work one-on-one and discuss each color decision aloud.
- Classroom: Have small groups share primary paints and compare results.
- Online or digital: Use a digital painting tool with an eyedropper or color-mixing feature, while discussing how digital colors differ from physical pigments.
- Limited materials: Use colored pencils or crayons to create the wheel, then explain the expected paint mixtures in writing.
Conclusion: Closure and Recap — 10 Minutes
Three-Part Recap
Ask the learner to complete these statements:
- “The traditional pigment primary colors are ___, ___, and ___.”
- “A secondary color is made by ___.”
- “A tertiary color is made by ___.”
Reflection Questions
- Which mixture surprised you most?
- Which color was the most difficult to balance using equal parts?
- Why might two artists get slightly different results even when following the same recipe?
- How could a color wheel help an artist plan a painting or design?
Close by reinforcing the main idea:
“A small set of carefully chosen pigments can produce a much larger family of colors. By measuring equal parts and arranging the results in order, artists can understand and control relationships among hues.”
Optional Follow-Up Project
Create a small artwork based on a chosen color relationship:
- Warm palette: red, orange, yellow, and their tertiary neighbors
- Cool palette: green, blue, violet, and their tertiary neighbors
- Neighboring-color palette: three or four colors beside one another on the wheel
- Full-spectrum design: include all twelve hues in a repeated pattern
Under the artwork, list the colors used and identify each as primary, secondary, or tertiary.
