Obsidian Gallery
Five stops tuned to sit together without fighting — #006b96 ink anchors the set, #a2ddff opens it up, and #0097d1, #3ab4ef, #65c2f5 cross the middle in a complementary arrangement. Obsidian Gallery suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
