3D Primary Colour Mixing (Additive)

Explore additive colour mixing with three coloured spotlights (Red, Green, Blue). Adjust their intensity and position to see how overlapping lights blend to form secondary colours and white light. Rotate the 3D scene to view from any angle.

💡 Additive Mixing

Additive colour mixing occurs when coloured lights overlap. The more light is added, the brighter the result becomes — combining all three primary colours at full intensity produces white light.

🎨 vs. Subtractive Mixing

Subtractive mixing uses pigments (Cyan, Magenta, Yellow) and absorbs light. Mixing all pigments produces black. Additive mixing uses light sources and is the basis of screens and projectors.
