Steely Ridge
Five stops tuned to sit together without fighting — #7d0003 ink anchors the set, #ee8c7e opens it up, and #a93d33, #c8594d, #cf7064 cross the middle in a analogous arrangement. Steely Ridge suits ceramics and home goods shot against white seamless. The darkest and lightest stops clear AA as a text pair.
