Blue Hour palette
Rocky Bookshop
A quiet five-stop blue hour arc with a confident middle — #004859 carries the weight and #6fb7cf carries the air, with #00728c, #308da8 and #539bb2 bridging in complementary formation. Built for podcast cover art at sixty pixels square. The darkest and lightest stops clear AA as a text pair.
