Blue Hour palette
Oyster Heath
A quiet five-stop blue hour arc with a confident middle — #0059ad carries the weight and #a7ceff carries the air, with #2d83e5, #51a0ff and #72b1ff bridging in complementary formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
