What Is Hex Color Code?
A hex color code is a six-digit hexadecimal number (like #2F95E9) defining a color by its red, green and blue components.
A hex color code represents a color as three pairs of hexadecimal digits for red, green and blue, each ranging from 00 (0) to FF (255). #FF0000 is pure red, #FFFFFF white, #000000 black, and #2F95E9 the blue used in The 360 Tools logo.
Hex is equivalent to RGB notation — #2F95E9 equals rgb(47, 149, 233) — and remains the most common color format in web design, CSS and design tools. Shorthand three-digit codes like #F00 expand each digit (#FF0000).
