Blue Hour palette
Violet Crater
A quiet five-stop blue hour arc with a confident middle — #00657e carries the weight and #7fd9f8 carries the air, with #0091b4, #39add1 and #62bbda bridging in triadic formation. Built for hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
