Seafoam Lighthouse
Five stops tuned to sit together without fighting — #00517c ink anchors the set, #75c3fa opens it up, and #007bb8, #3397d6, #58a6dc cross the middle in a monochromatic arrangement. Seafoam Lighthouse suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
