Predicted metallicities for our Gaia+2MASS+WISE giants as a function of WISE color W1 − W2 are shown in the top row. The bottom row shows histograms of the predictions for LMC (SMC) in blue (orange), selecting stars that fall within a 12° (8°) aperture of the respective Cloud. These histograms have been normalized to encompass an area of unity. In the leftmost panels, there is a population of stars for which our predictions are spurious, causing a pile-up at ∼−1 dex. These stars are the reddest stars in our sample and can be removed through the application of the 2MASS color cuts described in the text. The AGB stars form a bifurcation in the metallicity–color sequence owing to the unusual properties of the WISE isochrone tracks in which the AGB stars sharply turn red, crossing RGB tracks of lower metallicities. In turn, this causes a bimodality in metallicity at fixed WISE color. The final column shows the effect of requiring the mean feature space distance ﹩\left\langle {D}_{{NN}}\right\rangle ﹩ to be less than 0.06. It largely removes the stars that are extremely blue, culling those stars whose predictions spuriously converge to ∼−0.8 dex.
