Petrichor palette
Birch Library
Five stops tuned to sit together without fighting — #004c4d ink anchors the set, #71bdbd opens it up, and #007879, #329394, #55a0a1 cross the middle in a split-complementary arrangement. Birch Library suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
