Blue Hour palette
Birch Archive
A quiet five-stop blue hour arc with a confident middle — #007188 carries the weight and #8ee5ff carries the air, with #009ebe, #3cbbdb and #68c9e5 bridging in split-complementary formation. Built for music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA for large text.
