Opal Kiln
Five stops tuned to sit together without fighting — #006d69 ink anchors the set, #83e2db opens it up, and #009b95, #3bb7b1, #65c5be cross the middle in a analogous arrangement. Opal Kiln suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
