Allow anonymous usage statistics? UNQIRO would count only which tool was used, whether it finished and which links between the tools and the Format Lab were followed. Your files, text and results are never included, and this use is not counted.
Colors, converted exactly
- Five ways to write one color: HEX, RGB, HSL, HWB and OKLCH, with alpha. Type any of them, or a CSS name like rebeccapurple; every other form follows.
- Computed, not looked up: Conversions use the published formulas (sRGB, OKLab); values are rounded only for display, so a round trip stays the same color.
- Outside the screen’s range: OKLCH can describe colors most screens cannot show. HEX, RGB and HSL are then clipped to sRGB, and the page says so.
Frequently asked questions
Why use OKLCH?
Its lightness matches what eyes see much better than HSL, so steps in lightness or hue look even. Modern browsers support it in CSS.
Is #abc the same as #aabbcc?
Yes. Short HEX doubles every digit; #abcd adds an alpha digit.
