Stone Cellar
Five stops tuned to sit together without fighting — #005f99 ink anchors the set, #9cd1ff opens it up, and #1889d5, #3fa5f3, #64b5f8 cross the middle in a tetradic arrangement. Stone Cellar suits ceramics and home goods shot against white seamless. The darkest and lightest stops clear AA for large text.
