Blue Hour palette
Woodsmoke Foundry
Five blue hour stops with room to breathe — #7f1a00 grounds, #bd3412 and #dd5334 do the talking, #e36e53 softens, #ff8d72 lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
