Nebula palette
Terracotta Library
Five nebula stops with room to breathe — #004c4e grounds, #00787a and #329395 do the talking, #55a0a2 softens, #71bdbe lifts. The monochromatic bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
