Leaden Porch
Five stops tuned to sit together without fighting — #005484 ink anchors the set, #7cc5ff opens it up, and #007dc2, #3399e0, #59a8e5 cross the middle in a tetradic arrangement. Leaden Porch suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
