Tranquil Courtyard
Five stops tuned to sit together without fighting — #800c00 ink anchors the set, #fd8975 opens it up, and #b73523, #d6533f, #dd6d5a cross the middle in a split-complementary arrangement. Tranquil Courtyard suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
