Blue Hour palette
Daybreak Atelier
Five stops tuned to sit together without fighting — #005682 ink anchors the set, #80c8fb opens it up, and #2180b8, #439cd6, #63abdc cross the middle in a tetradic arrangement. Daybreak Atelier suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
