Blue Hour palette
Chiffon Pavilion
Five blue hour stops with room to breathe — #004a7b grounds, #1973b4 and #3b8fd2 do the talking, #5b9ed7 softens, #77baf6 lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
