Lunar Foundry
Five stops tuned to sit together without fighting — #9e2201 ink anchors the set, #ffb09d opens it up, and #cb553b, #ea7156, #f18971 cross the middle in a complementary arrangement. Lunar Foundry suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
