Effect of microlensing on the apparent F125W–F160W color (﹩-2.5\times {\mathrm{log}}_{1}0({\rm{F}}125{\rm{W}}/{\rm{F}}160{\rm{W}})﹩) of SN Refsdal from simulations, as a function of rest-frame time since explosion. Shown are 1000 random realizations of an SN 1987A–like photosphere expanding linearly in a stellar microlensing field. These curves demonstrate that microlensing magnification will affect the total F125W and F160W flux from the photosphere almost equally, resulting in color changes of <0.05 mag.
