We put a new spin on Khovanov--Rozansky homology. That is, we equip ⁿ-colored sl₂₍ Khovanov--Rozansky homology with an involution whose 1-eigenspaces are link invariants. When n=1, 2, 3 (and assuming technical conjectures for n 4), we prove that this refined invariant categorifies the spin-colored so₂₍+₁ quantum link polynomial. Along the way, we partially develop the theory of quantum so₂₍+₁ webs and make contact with quantum groups.
