Ember Gallery
Five stops tuned to sit together without fighting — #850d0c ink anchors the set, #f69386 opens it up, and #b1443a, #d06054, #d7776b cross the middle in a triadic arrangement. Ember Gallery suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
