Blue Hour palette
Nightfall Estuary
Five stops tuned to sit together without fighting — #156696 ink anchors the set, #a3d8ff opens it up, and #4b90c0, #67acde, #81bbe6 cross the middle in a monochromatic arrangement. Nightfall Estuary suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
