💡Understanding Additive Color Mixing

Additive color mixing occurs when different colored lights are combined together. This is the principle behind digital displays, stage lighting, and LED screens. Unlike mixing paints (subtractive), mixing lights adds wavelengths together.

The three primary colors of light are Red, Green, and Blue (RGB). When all three are combined at full intensity, they create white light.
