Comparison between the color gradients retrieved with EAZY rest-frame fluxes and observed fluxes as a function of redshift and color coded with the uncertainty on the color gradient retrieved using observed fluxes. The top panel shows the U − V color difference, while the bottom panel shows the V − J color difference. In the top left corner of each panel we present the median and standard deviation of the color gradient difference, while in the bottom right corner we show the median uncertainty on the two color gradients. Solid black lines show the standard deviation of the difference between the two color gradients as a function of redshift.
