Blue Hour palette
Hushed Ridge
Five stops tuned to sit together without fighting — #006499 ink anchors the set, #a0d5ff opens it up, and #3d8ec6, #5aaae4, #78b9eb cross the middle in a monochromatic arrangement. Hushed Ridge suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
