Plum Archive
Five stops tuned to sit together without fighting — #006c99 ink anchors the set, #a8ddff opens it up, and #1498d3, #41b5f1, #69c4f7 cross the middle in a monochromatic arrangement. Plum Archive suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
