Blue Hour palette
Grape Cabin
A quiet five-stop blue hour arc with a confident middle — #00689b carries the weight and #a6daff carries the air, with #2e93d0, #4fafee and #71bff4 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.
