Frequently asked questions
- Is the CMYK value exact?
- It is the plain mathematical conversion from screen RGB, so treat it as a starting point. A print shop converts with a printer profile (ICC) for the paper and inks, and the real result will differ, mostly for bright greens and blues. Ask your printer for a proof.
- What is OKLCH and when should I use it?
- OKLCH describes a color by lightness, chroma (how vivid) and hue, tuned so equal steps look equal to the eye. It is valid CSS in current browsers, and it is handy for building palettes because changing lightness does not shift the hue.
- What is the difference between HSL and HSV?
- Both describe hue and saturation. HSL uses lightness and HSV uses value (brightness). CSS supports HSL.
- Can I paste a color name?
- Yes, any CSS color name works, such as tomato or rebeccapurple.
- Is anything sent to a server?
- No. Everything runs in your browser.
