Left: F1500W/F560W−F770W/F560W color–color diagram for all clumps detected in the MIRI images. For sources without a detection in the F1500W image, upper limits are indicated by downward arrows. Right: for comparison, the same diagram but showing the colors of local LIRG nuclei derived from synthetic photometry of the Spitzer/IRS low-resolution spectra. The data points are color-coded by the 6.2 μm PAH EQW measured from the spectra. The color derived from the total flux of the MIRI clumps in the left panel is shown as a star. In the Spitzer slit that covers the merger-induced dusty region, IIZw096 has one of the reddest F1500W/F560W colors among local LIRGs.
