Cozy Lighthouse
Five stops tuned to sit together without fighting — #006973 ink anchors the set, #81dde9 opens it up, and #0096a4, #3ab2c0, #63c0cc cross the middle in a analogous arrangement. Cozy Lighthouse suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
