Blue Hour palette
Seafoam Junction
Five stops tuned to sit together without fighting — #8b1a00 ink anchors the set, #ff9983 opens it up, and #c93616, #e95537, #ef7257 cross the middle in a monochromatic arrangement. Seafoam Junction suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
