Silken Cottage
Five stops tuned to sit together without fighting — #073a82 ink anchors the set, #80aaec opens it up, and #3563ab, #4f7ec8, #658ece cross the middle in a complementary arrangement. Silken Cottage suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
