Cobalt Prairie
Five stops tuned to sit together without fighting — #732400 ink anchors the set, #ed9373 opens it up, and #a84620, #c6613d, #ce7758 cross the middle in a split-complementary arrangement. Cobalt Prairie suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
