We show a similar result when nodes are restricted to choose their color from a list of allowed colors: given an $m$-coloring in a directed graph of maximum outdegree $\\beta$, if every node has a list of size $\\Omega(\\beta^2 (\\log \\beta+\\log\\log m + \\log \\log |\\mathcal{C}|))$ from a color space $\\mathcal{C}$ then they can select a color in two rounds in the LOCAL model.
