Terracotta Moor
Five stops tuned to sit together without fighting — #004c5a ink anchors the set, #72bccf opens it up, and #00778c, #3292a8, #55a0b2 cross the middle in a split-complementary arrangement. Terracotta Moor suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
