A Hexadecimal color code is a six-digit, three-byte number used in HTML, CSS, and SVG to represent colors. The bytes represent the red, green, and blue components of the color. Each byte is represented as a pair of characters from 00 to FF, corresponding to values 0-255.
RGB (Red, Green, Blue) is an additive professional model where light is combined to create color. HSL (Hue, Saturation, Lightness) is a cylindrical-coordinate representation of RGB and is often more intuitive for designers to manipulate brightness or saturation.
