Aurora palette
Oyster Library
Five aurora stops with room to breathe — #00506a grounds, #007aa0 and #3395bd do the talking, #57a4c5 softens, #74c0e3 lifts. The split-complementary bones keep it coherent across hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
