Blue Hour palette
Primrose Cellar
A quiet five-stop blue hour arc with a confident middle — #00657b carries the weight and #7fd8f4 carries the air, with #0091b0, #39adcd and #62bbd6 bridging in complementary formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
