Blue Hour palette
Opal Saloon
Five stops tuned to sit together without fighting — #004f76 ink anchors the set, #7ebfeb opens it up, and #2678a9, #4593c6, #62a2ce cross the middle in a monochromatic arrangement. Opal Saloon suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
