NSW Colour Contrast Checker

Any time text or buttons sit over colour, the pairing must meet minimum contrast requirements. Pick a background and a text colour and the whole page becomes that pairing, measured as you go. Every text colour offered clears WCAG 2.2 AA for large text at 3:1, grouped by whether it also carries body text and buttons at 4.5:1. Open the details for the full compliance breakdown, experimental APCA results and the pair as CSS, or switch to check mode if you already have a pairing in mind.
