The double copy relates gravity to gauge theory, but how does this extend to semiclassical phenomena such as Hawking radiation? I will show that the thermal spectrum of a collapsing black hole admits a gauge-theory origin: classical non-abelian sources radiate in a way that is thermal in color charge. This correspondence emerges both from an S-matrix description of particle production and from a complementary worldline analysis, and maps horizon thermodynamics to simple properties of color charge.
