Colors are represented in different ways. HEX (e.g. `#FF5733`) is what you see in HTML and CSS. RGB (Red, Green, Blue) uses three numbers from 0 to 255. HSL (Hue, Saturation, Lightness) is useful when you want to tweak hue or make a color lighter or darker. Design tools might give you one format; your code or another tool might need another. A color converter takes a color in one format (HEX, RGB, or HSL) and gives you the equivalent in the others. So you’re not digging through docs or doing the maths by hand. You paste or type the value, and you get what you need.
When do you use it? When you’re moving from design to code and the design tool exports HEX but your stack expects RGB or HSL. When you’re matching a color from a reference—image, brand guide, another site—and you need it in a format your project uses. When you want to create variations: in HSL, you can nudge the lightness and get a lighter or darker shade, then convert back to HEX or RGB for your CSS or design file. When you’re checking accessibility and your contrast tool wants a specific format. Consistency across a site or app often comes down to using the same color values everywhere; a converter makes sure you’re not mixing formats by mistake.
The maths between HEX, RGB, and HSL isn’t terrible, but it’s easy to slip—especially with HEX’s mix of letters and numbers. A converter does it once and correctly. You get a preview of the color plus the values in the format you need. Copy, paste, done.
Our color converter is free and runs in your browser. Enter a color in HEX, RGB, or HSL; get the other formats. No sign-up, no data sent anywhere. Use it for design, code, or any time you need a color in a different format.
