Choosing a format

Use HEX for static brand values and handoff, OKLCH for anything you intend to manipulate in CSS, and Display-P3 when you want saturated accents to bloom on modern screens while keeping an sRGB fallback.

Understanding the numbers

OKLCH reads as lightness (0–1 or 0–100%), chroma (0 to roughly 0.37) and hue in degrees. LAB and LCH are CIE spaces with the same intent but poorer hue uniformity in blues. HSV and HWB are picker-friendly reparameterisations of RGB, not perceptual spaces.

Wide-gamut safety

If a color needs Display-P3 or Rec.2020, ship it inside an @supports (color: color(display-p3 1 1 1)) block or use oklch() with values that clamp gracefully. The converter always shows the clamped sRGB equivalent so you know what non-P3 users will see.

Frequently asked questions

Which color formats can I convert between?
HEX, RGB, HSL, HSV, HWB, LAB, LCH, OKLAB, OKLCH, CMYK and Display-P3. Type or paste any of them into the input and every other format updates instantly.
Is OKLCH better than HSL for CSS?
For manipulation, yes. OKLCH lightness matches perception, so lighten/darken and hue rotation behave predictably, and it can express colors outside sRGB for wide-gamut displays. HSL remains fine for static values.
Why does my color show an out-of-gamut warning?
Some LAB, LCH, OKLCH and Display-P3 values are more saturated than an sRGB screen can show. The badge tells you which gamut the color needs; the HEX and RGB outputs are clamped into sRGB so they stay renderable.
How is CMYK calculated?
With the standard device-independent formula from sRGB. Use it for rough reference only — real print output depends on an ICC profile, paper and press.
