How to use the color converter
- Use the picker or type a HEX code.
- Copy the HEX, RGB or HSL value by tapping it.
HEX vs RGB vs HSL
- HEX — six-digit web code like
#6366f1. - RGB — red, green, blue values (0–255).
- HSL — hue, saturation, lightness — easiest for tweaking shades.
Benefits
- Converts between HEX, RGB and HSL with a live color picker.
- Instant, and it doubles as a quick lesson in how each format works.
- Runs in your browser — nothing is uploaded.
- Free and unlimited.
Limitations to know
- It works in on-screen sRGB color, not print (CMYK) or wide-gamut color spaces.
- Alpha (opacity) handling is basic.
- The color you see depends on your display’s calibration, so two screens may differ.
Common mistakes to avoid
- Expecting an on-screen HEX value to match a printed CMYK color exactly.
- Forgetting the leading "#" when pasting a HEX value elsewhere.
- Confusing HSL’s hue (measured in degrees) with a percentage.
Alternatives
