Task 5 - Group B: The Digital Creator
Focus: digital art and pixels - the RGB system. What happens when we look deeper into an image?
Step 1 - Check the AI explanation

AI prompt
"How do digital screens create colour using RGB?"
"Every pixel on a screen is made of three tiny lights: Red, Green, and Blue. By mixing different amounts of these three colours of light, a screen can create almost any colour you see - including white, when all three are at full brightness."
Does it make sense? Is something missing?
Good instinct - it's accurate for how RGB mixing works, but it doesn't mention that screens don't store colour like paint does; they generate it fresh with light, every single frame.
Step 2 - Mix Red, Green and Blue light

Tap the lights to mix a colour.
What you discovered
An image is made of tiny coloured units. Screens don't store colours - they create them, live, using Red, Green and Blue light.
What happens in Task 5
A 5-minute Phase 3 - Investigation activity as "Group B - The Digital Creator." Students verify an AI explanation of RGB, then use an interactive light-mixer to combine Red, Green and Blue and see the resulting colour.
🎯 Learning objectives
Analyse how digital tools shape modern artistic expression, and understand that screens create colour additively from light rather than storing it like pigment.
♿ SEN Adaptations

- High-contrast mode available for the colour swatch
🖨️ No-Tech Format
- Teacher demonstrates with red, green and blue coloured cellophane or torches
- Students overlap the coloured light by hand and observe the mixed colour
