Sunlit Courtyard
Five stops tuned to sit together without fighting — #a00042 ink anchors the set, #ffa8b8 opens it up, and #d04269, #f06083, #f67b96 cross the middle in a tetradic arrangement. Sunlit Courtyard suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
