HEX vs RGB vs HSL: Which Color Format Should You Use?

Confused by color codes? We break down the differences between HEX, RGB, and HSL, and when to use each one in your design workflow.

If you've ever opened a design tool or inspected a website's code, you've seen them: #FF5733, rgb(255, 87, 51), hsl(10, 100%, 60%). They all represent the same color, but they speak different languages.

HEX: The Web Standard

HEX (Hexadecimal) is the most common format for web design. It uses a six-digit code to represent Red, Green, and Blue values. It's compact and easy to copy-paste, making it a favorite for developers.

RGB: The Digital Native

RGB (Red, Green, Blue) is how screens actually work. By mixing these three colors of light, you can create over 16 million colors. It's intuitive if you understand additive color mixing, but hard to tweak intuitively.

HSL: The Human Friendly Choice

HSL (Hue, Saturation, Lightness) is designed for humans, not machines.

  • Hue: The color itself (0-360 degrees on the color wheel).
  • Saturation: How vivid the color is (0-100%).
  • Lightness: How bright the color is (0-100%).
Want a lighter version of a color? Just increase the Lightness. It's that simple.
