Aurora palette
Fern Fen
A quiet five-stop aurora arc with a confident middle — #006a6b carries the weight and #81dfdf carries the air, with #009899, #3ab4b5 and #64c2c2 bridging in split-complementary formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
