What are RGB and HEX?
RGB stands for Red, Green, Blue. It's an additive color model where colors are created by combining red, green, and blue light. Each value ranges from 0 to 255, where 0 means no light and 255 means full intensity. RGB is used for digital screens, monitors, TVs, and cameras.
HEX (hexadecimal) is a six-digit code representing RGB values. The format is #RRGGBB, where RR is hex for red, GG for green, BB for blue. For example, #FF0000 is pure red (RGB: 255,0,0).
