About RGB and HEX Colors
RGB (Red, Green, Blue) and HEX (Hexadecimal) are two common color formats used in web development and design. RGB uses decimal values (0-255) for each color channel, while HEX uses hexadecimal values (00-FF) in a compact format. Both represent the same colors but in different notations.
