About this tool

About Color Converter

The Color Converter translates a colour between HEX, RGB and HSL formats and shows a live preview swatch. Pick a colour with the colour picker or type a value, and the other formats update immediately.

Designers and developers switch between formats all the time. HEX is common in CSS and design tools, RGB describes screen light and HSL makes it easy to adjust hue, saturation and lightness. Having all three side by side saves time when matching a brand colour.

Designers, developers and writers handle color in different formats. HEX is common in CSS, RGB describes screen light and HSL makes it easier to adjust lightness and saturation. The Color Converter translates between them instantly.

Choosing a color also means checking contrast. Text needs enough difference from its background to stay readable, especially for people with low vision, so test important combinations before you commit to them.

Frequently Asked Questions

What is the difference between HEX, RGB and HSL?
HEX is a compact six-digit code, RGB gives red, green and blue values and HSL describes hue, saturation and lightness.
How do I read a HEX colour?
A HEX code like #3977F6 has three pairs of digits that represent the red, green and blue amounts in base sixteen.
Why use HSL?
HSL makes it easier to create lighter, darker or more muted versions of a colour by changing one value at a time.
Will colours look the same on every screen?
Displays differ in calibration and brightness, so the same value can look slightly different across devices.
Can I type a short HEX like #fff?
Short three-digit HEX values are common in CSS and expand to six digits, for example #fff means #ffffff.
Is anything uploaded?
No. All conversions happen in your browser.
