Blue Hour palette
Brindle Prairie
Five stops tuned to sit together without fighting — #004b8e ink anchors the set, #84bcff opens it up, and #1b73cb, #3c8fe9, #5ca0ed cross the middle in a tetradic arrangement. Brindle Prairie suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
