Mixing Secondary Colours

Active experimentation in mixing primary colours to create orange, green, and purple. Students apply these to a landscape painting.

About This Topic

Mixing Secondary Shades is where the 'magic' of colour happens for Year 1. Building on their knowledge of primary colours, students now learn the recipes for orange, green, and purple. This aligns with the KS1 National Curriculum goal of using painting to develop and share ideas. By applying these new colours to a landscape painting, students see the practical application of their mixing, using green for grass or orange for a sunset.

This topic is highly experimental. It encourages children to be 'colour scientists', adjusting the ratios of paint to achieve the perfect shade. Students grasp this concept faster through structured discussion and peer explanation, as they compare their mixed shades and describe the 'recipes' they used to create them.

Key Questions

1. Construct the perfect shade of green by mixing blue and yellow.
2. Predict the outcome if you mix all three primary colours together.
3. Compare the secondary colours you created to colours found in nature.

Learning Objectives

• Create secondary colours (orange, green, purple) by mixing primary colours.
• Compare the resulting secondary colours to colours found in nature.
• Apply mixed secondary colours to a landscape painting.
• Explain the process of mixing primary colours to achieve a specific secondary colour.

Before You Start

Identifying Primary Colours

Why: Students must be able to identify red, yellow, and blue before they can begin mixing them.

Basic Painting Techniques

Why: Students need to be comfortable holding a brush and applying paint to paper to engage in the mixing and painting activities.

Key Vocabulary

Primary Colours	The basic colours red, yellow, and blue. These colours cannot be made by mixing other colours.
Secondary Colours	Colours made by mixing two primary colours together. For example, green is made by mixing blue and yellow.
Mixing	Combining two or more colours together to create a new colour.
Shade	A colour made darker by adding black. In this context, it refers to the specific hue achieved through mixing.

Watch Out for These Misconceptions

Common Misconception

Mixing all colours makes black.

What to Teach Instead

Children often think adding more colours makes a darker, 'better' colour, but it usually results in brown or grey. A 'Messy Mix' experiment where they purposefully mix everything helps them see the 'mud' and understand why we mix only two primaries at a time for secondary shades.

Common Misconception

You need equal amounts of both primary colours.

What to Teach Instead

Students often find that a tiny bit of blue overpowers a lot of yellow. Through hands-on 'ratio testing', they learn that some colours are 'stronger' than others. Peer sharing of these 'strong colour' discoveries helps the whole class adjust their mixing technique.

Active Learning Ideas

Inquiry Circle: The Secret Recipe

In pairs, students are given a 'target' secondary colour (e.g., a specific shade of green). They must work together to mix primary colours, recording how many 'scoops' of each they used to reach the target.

Stations Rotation: Landscape Layers

Set up three stations: 'The Orange Sun', 'The Green Field', and 'The Purple Mountain'. At each station, students mix the required secondary colour and add one element to a shared class landscape mural.

Think-Pair-Share: Colour Predictions

Before mixing, the teacher holds up two primary colours. Students whisper to a partner what colour they think will appear. After the mix, they discuss if the result was what they expected and why.

Real-World Connections

• Graphic designers use colour mixing principles to create specific brand colours for logos and advertisements. They must precisely mix inks to match a desired hue.
• Automotive paint technicians mix colours to repair car scratches and dents, ensuring the new paint perfectly matches the original factory colour of the vehicle.
• Illustrators creating children's books often mix colours to achieve vibrant and appealing palettes for their characters and settings, considering how colours evoke emotions.

Assessment Ideas

Exit Ticket

Provide each student with a small card. Ask them to draw a simple landscape and label one area with the primary colours they would mix to create the secondary colour used there. For example, 'Grass: Blue + Yellow'.

Discussion Prompt

Hold up two different shades of green paint, one clearly made with more yellow than the other. Ask students: 'Which of these greens looks more like the grass in our school field? How did you make your green? Can you explain the 'recipe' for your colour?'

Quick Check

Observe students as they mix paints. Ask individual students: 'What two colours are you mixing right now? What colour do you predict you will make?' Note their ability to predict and identify primary colours.

Frequently Asked Questions

How can I prevent the paint from getting too messy?

Provide small amounts of paint on individual palettes or plastic lids. Use 'one brush per colour' or teach a strict 'wash and dry' routine for brushes. Giving students a specific 'mixing zone' on their paper or palette also helps contain the experimentation.

What if the purple looks too dark or brown?

Purple is the hardest secondary colour to mix with standard school paints. Ensure you are using a 'cool' red (like crimson) and a 'warm' blue (like ultramarine). If it looks brown, it's often because there is a hint of yellow in one of the primaries. Adding a tiny bit of white can help the purple hue show through.

How can active learning help students understand secondary colours?

Active learning turns colour mixing into a social and scientific inquiry. When students work in pairs to find a 'secret recipe' or contribute to a 'landscape mural', they are constantly evaluating their results against others. This peer feedback loop helps them understand that colour is relative and that small changes in ingredients lead to big changes in the final shade.

How does this topic link to Geography?

By using secondary colours to paint landscapes, students are identifying physical features like hills, forests, and sunsets. This reinforces the Year 1 Geography goal of identifying key physical features of the environment while using their new artistic skills to represent them.
