Blue Hour palette
Sleepy Crater
A quiet five-stop blue hour arc with a confident middle — #004459 carries the weight and #6db3cf carries the air, with #006e8d, #2f89a9 and #5197b2 bridging in tetradic formation. Built for dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
