Nebula palette
Pewter Library
Five stops tuned to sit together without fighting — #006f61 ink anchors the set, #84e5d2 opens it up, and #009e8a, #3bbba5, #66c7b5 cross the middle in a tetradic arrangement. Pewter Library suits music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA for large text.
