Glassy Cellar
Five stops tuned to sit together without fighting — #004f63 ink anchors the set, #73c0da opens it up, and #007a97, #3395b3, #57a3bd cross the middle in a monochromatic arrangement. Glassy Cellar suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
