Text/background contrast: 10.25:1. This is one measured pair, not a guarantee for the whole palette. Check every actual text/background pairing against WCAG AA. Prefer readable combinations from the original colors, keep visible keyboard focus, and never communicate state through color alone. If no original pairing meets the requirement, propose a separately labeled derived color with its original HEX, proposed HEX, purpose and measured contrast. Never overwrite the source palette.
