What it is
RGB is the basic color model for screens. Instead of mixing material pigments, it adds colored light: red, green, and blue channels combine to produce the colors we see on phones, monitors, and projectors.
Basics
- Red, green, and blue are the additive primaries used by most digital displays.
- Adding all three at full intensity produces white light on screen.
- RGB is useful for web design because CSS colors, images, and displays are built around screen output.
Notes for later expansion
- RGB describes emitted light, not paint or ink.
- On Color Lore, vivid hue-map wheels are screen/RGB-style teaching diagrams unless labelled otherwise.
