  We show that the anti-ferromagnetic Potts model on trees exhibits strong
spatial mixing for a near-optimal range of parameters. Our work complements
recent results of Chen, Liu, Mani, and Moitra [arXiv.2304.01954] who showed
this to be true in the infinite temperature setting, corresponding to uniform
proper colorings. We furthermore prove weak spatial mixing results
complementing results in [arXiv.2304.01954].
