    Contrast Lab: see where your colours pass, not just whether they do

    Pick a text colour and you get every possible background on a plane of hue and lightness (OKLCH), with lines where contrast crosses 3, 4.5 and 7 to 1. Drag the handle or use the arrow keys. Nudge either colour by the smallest lightness change that passes, then copy the CSS, a PNG card or a link. Limitation: it uses WCAG 2.x ratios only, not APCA. Try your brand colour and tell us what surprised you.
