Mustard Dune
Five stops tuned to sit together without fighting — #005288 ink anchors the set, #87c3f8 opens it up, and #347bb6, #5097d3, #6ca6da cross the middle in a tetradic arrangement. Mustard Dune suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
