Step 1: Define additive color theory. The additive color model describes how light produces color. It is used in digital displays like monitors and televisions. The primary colors in this system are Red, Green, and Blue (RGB).
Step 2: Understand how secondary colors are formed. In the additive model, colors are created by adding light. When two primary colors of light are mixed, they produce a secondary color.
Step 3: Apply the rule for Red and Green. The mixing of red light and green light in equal intensity produces yellow light.
The full set of combinations is:
Red + Green = Yellow
Red + Blue = Magenta
Green + Blue = Cyan
Red + Green + Blue = White
