Blue Hour palette

Leafy Bluff

Five blue hour stops with room to breathe — #0061b3 grounds, #3a8ce4 and #5ca9ff do the talking, #7db9ff softens, #b2d5ff lifts. The tetradic bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
