Marble Square
Five stops tuned to sit together without fighting — #295700 ink anchors the set, #8fca6f opens it up, and #428400, #5da02f, #74ad53 cross the middle in a tetradic arrangement. Marble Square suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
