Open tool →Build a workflow around the result
Start with a palette, then verify foreground and background pairs with the contrast checker. Check real component states before publishing. Test downloaded QR codes at their intended size and verify the destination. A passing color pair does not certify a complete page. Compare colors on actual devices and preserve focus indicators, meaningful labels and keyboard access as you apply the palette.
