What is a hex color code?

A hex color code (hexadecimal color code) is a way to represent colors in digital design using six characters that combine numbers (0-9) and letters (A-F). For example, #FF5733 represents a shade of orange-red. Each pair of characters controls red, green, and blue intensity, allowing over 16 million color combinations. Hex codes are the standard format for specifying colors in web design, graphic design, and digital art because they're compact, precise, and universally supported by browsers and design software.
