Color gradients as a function of redshift for quiescent galaxies in four stellar mass bins and color-coded with global A_V. The top row shows the U − V color gradients (Δ(U − V) = (U − V)_{1 < r/Re < 2} − (U − V)_r < Re), and the bottom row shows the V − J color gradients (Δ(V − J) = (V − J)_{1 < r/Re < 2} − (V − J)_r < Re). The black error bars in the lower left (right) corner of each panel show the median uncertainty on the color gradients for all the galaxies in that stellar mass bin with z < 1.5 (z > 1.5). The solid black lines show the running median, and the dashed lines show the 16−84 percentile range. The squares show the median color in redshift bins with a width of 0.25, and the (generally negligible) error bars represent the statistical uncertainty $\sigma /\sqrt{N}$. Both colors show a mild stellar mass dependence and a mild or absent redshift evolution. Just galaxies with M_★ < 10^10.5 M_⊙ show a significant evolution of Δ(V − J) with redshift.
