Crimson, Teal and Denim lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.
Crimson #dc143c

Teal #008080

Denim #1560bd
shippedDesigners have shipped Denim with #660a3b: 3 real palettes, including Heinz's brand system and Hinge's brand system, as the accent.
Forest Green #228b22
split-complementForest Green is a split-complement of #660a3b: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for #660a3b: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Copper #b87333
shippedDesigners have shipped Copper with #660a3b: two real palettes: Bramble and Chipotle's brand system, as the supporting colour.
Cream #fffdd0
neutralCream is the surface #660a3b wants: a warm off-white that shares its undertone, so #660a3b reads softer on it than on pure white.
Pale Goldenrod #eee8aa
shippedTwo real palettes: Macaron and Blossom put Pale Goldenrod beside #660a3b, as the accent.
