Vernal Square
Five stops tuned to sit together without fighting — #7b0400 ink anchors the set, #fe7f6c opens it up, and #b82215, #d84434, #de6251 cross the middle in a tetradic arrangement. Vernal Square suits yoga studio schedules pinned to a corkboard. The darkest and lightest stops clear AA as a text pair.
