Dewey Beacon
Five stops tuned to sit together without fighting — #006d95 ink anchors the set, #a3deff opens it up, and #4097c2, #5eb3e0, #7cc2e8 cross the middle in a monochromatic arrangement. Dewey Beacon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
