Frequently asked questions

What is OKLCH?

A perceptual color space where equal steps in lightness look equally different, which makes it great for building palettes.

What contrast ratio do I need?

WCAG AA needs 4.5:1 for normal text and 3:1 for large text; AAA needs 7:1.

Is CMYK exact for print?

No. It's a simple formula; real print colors depend on the printer's color profile.
