Brindle Estuary
Five stops tuned to sit together without fighting — #7b0032 ink anchors the set, #fa809b opens it up, and #b42855, #d4486e, #da6480 cross the middle in a tetradic arrangement. Brindle Estuary suits restaurant branding that works on signage and receipts alike. The darkest and lightest stops clear AA as a text pair.
