Blue Hour palette
Seafoam Boulevard
Five stops tuned to sit together without fighting — #912000 ink anchors the set, #ffa28b opens it up, and #c34b2f, #e2674b, #e98066 cross the middle in a triadic arrangement. Seafoam Boulevard suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
