Tranquil Brook
Five stops tuned to sit together without fighting — #004a74 ink anchors the set, #71baf2 opens it up, and #0073b0, #318fcd, #549ed4 cross the middle in a tetradic arrangement. Tranquil Brook suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
