What is RGB Color Model?
Definition
RGB (Red, Green, Blue) is an additive color model where colors are created by combining red, green, and blue light at different intensities (0-255). CSS uses rgb(255, 0, 0) notation. Adding all three at full intensity produces white.
Why It Matters
RGB is the fundamental color model for screens, monitors, and digital displays. Understanding RGB helps developers convert between color formats, create color palettes, and implement dynamic color manipulation in CSS and JavaScript.
