Caption: Fig. 6.

Same field as in Fig. 5 but constructed with the I band (F814W) data as the blue channel, the H band (F160W) as the red channel, and the mean of the I‐ and H‐band images as the green channel. Light contamination by the quasar images affects much less the lens galaxies, which are clearly visible, either in blue (spiral lens SP) or green (lens G). Note the blue spiral arm passing at the position of quasar image B. The objects marked with the question marks are probably structures in the PSF of the H‐band image. They are cleanly removed in the deconvolution in Fig. 3.
