Festival Foundry
Five stops tuned to sit together without fighting — #880d07 ink anchors the set, #fa9485 opens it up, and #b54538, #d46152, #db786a cross the middle in a split-complementary arrangement. Festival Foundry suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
