Blue Hour palette
Ebony Alley
Five stops tuned to sit together without fighting — #00657c ink anchors the set, #7fd8f5 opens it up, and #0091b1, #39adce, #62bbd7 cross the middle in a triadic arrangement. Ebony Alley suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
