Polar Pavilion
Five stops tuned to sit together without fighting — #004c4a ink anchors the set, #71bdb8 opens it up, and #007874, #32938f, #55a09c cross the middle in a monochromatic arrangement. Polar Pavilion suits newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
