Tranquil Beacon
Five stops tuned to sit together without fighting — #004171 ink anchors the set, #6baff1 opens it up, and #0068b0, #2e83ce, #4f93d3 cross the middle in a complementary arrangement. Tranquil Beacon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
