Blue Hour palette
Firstlight Plaza
A quiet five-stop blue hour arc with a confident middle — #006288 carries the weight and #89d5fe carries the air, with #2b8dba, #4ca9d7 and #6db8df bridging in complementary formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
