Hexadecimal Color Code

A 6-character code representing a color as red, green, and blue values in base-16.

#FF5733 splits into three pairs: FF (red=255), 57 (green=87), 33 (blue=51). Each pair ranges from 00 (none) to FF (maximum). Pure red is #FF0000. Pure white is #FFFFFF. Pure black is #000000. Hex is a compact way to express RGB values — every hex color can also be written as rgb(r, g, b) or hsl(h, s%, l%).
