Blue Hour palette
Marble Brook
A quiet five-stop blue hour arc with a confident middle — #914537 carries the weight and #ffbcae carries the air, with #bc6f60, #da8a7a and #e39e90 bridging in split-complementary formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
