Generate secure random hex colors with a live preview.
Hexadecimal (hex) color codes represent colors using 6 digits, where each pair represents red, green, and blue (RGB) components.
Format: #RRGGBB
Each component ranges from 00 (no color) to FF (full color), providing over 16 million possible color combinations.
Use cases: Web design, CSS styling, graphics, UI/UX design, and any digital color specification.
What is a hex color code?
A hex color code is a 6-character string (preceded by #) that represents colors in RGB format. Each pair of characters represents red, green, and blue values from 00 (no color) to FF (full intensity). For example, #FF0000 is pure red, #00FF00 is pure green, and #0000FF is pure blue.
How many colors can hex codes represent?
Hex color codes can represent over 16 million colors (16,777,216 exactly). This comes from 256 values each for red, green, and blue channels: 256 × 256 × 256 = 16,777,216 possible color combinations.
How do I convert hex to RGB?
Convert each pair of hex digits to decimal. For #3498DB: 34 hex = 52 red, 98 hex = 152 green, DB hex = 219 blue. So #3498DB = rgb(52, 152, 219). Each hex pair uses digits 0-9 and letters A-F, where A=10 through F=15.
What's the difference between hex and RGB color formats?
Both represent the same colors differently. Hex uses base-16 notation (#RRGGBB), while RGB uses decimal values (rgb(0-255, 0-255, 0-255)). CSS accepts both formats. Hex is more compact, while RGB is easier to understand and manipulate programmatically.
