We construct a model of baryon diffusion which has the desired properties of causality and analyticity. The model also has the desired property of colored noise, meaning that the noise correlation function is not a Dirac delta function in space and time; rather, it depends on multiple time and length constants. The model can readily be incorporated in 3+1 dimensional 2nd order viscous hydro-dynamical models of heavy ion collisions, which is particularly important at beam energies where the baryon density is large.
