Firstlight Cellar
Five stops tuned to sit together without fighting — #004368 ink anchors the set, #70b1e1 opens it up, and #126b9f, #3686bc, #5595c3 cross the middle in a tetradic arrangement. Firstlight Cellar suits podcast cover art at sixty pixels square. The darkest and lightest stops clear AA as a text pair.
