Retro palette
Lupine Mill
A quiet five-stop retro arc with a confident middle — #173eb4 carries the weight and #9abbff carries the air, with #3e6cdf, #5789fe and #6f9bff bridging in complementary formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
