Tidal Alley
Five stops tuned to sit together without fighting — #942c00 ink anchors the set, #ffac91 opens it up, and #c7542e, #e6704b, #ed8868 cross the middle in a monochromatic arrangement. Tidal Alley suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
