Blue Hour palette
Sandy Archive
Five stops tuned to sit together without fighting — #005784 ink anchors the set, #7ec9ff opens it up, and #1981bd, #3e9ddb, #61ace1 cross the middle in a monochromatic arrangement. Sandy Archive suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
