Rosewood Estuary
Five stops tuned to sit together without fighting — #004777 ink anchors the set, #6fb7f6 opens it up, and #006fb5, #308bd3, #539ad8 cross the middle in a monochromatic arrangement. Rosewood Estuary suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
