Blue Hour palette
Cinder Marsh
A quiet five-stop blue hour arc with a confident middle — #00546f carries the weight and #76c6e8 carries the air, with #007fa5, #349bc2 and #59a9ca bridging in split-complementary formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
