Caption: Figure 5.

Color variation Δ(W1–W2) vs. W2 variability amplitude (ΔW2) of the MIR outburst galaxies. The histograms of Δ(W1–W2) and ΔW2 are shown in the right and bottom panels, respectively. We have divided the whole sample into five equal-sized subsamples sorted by ΔW2 and plotted the median Δ(W1–W2) of each subsample as red stars. The MIR variability shows an overall trend of RWB.
