Three-color ALMA 12 m array images of the Young clouds: W43-MM1 (panel a), W43-MM2 (panel b), G338.93 (panel c), G328.25 (panel d), G337.92 (panel e), and G327.29 (panel f), plotted at the same physical scale. Red and green display the continuum images at 1.3 and 3 mm, respectively, with the green color for the longer, 3 mm, wavelength because the 3 mm emission is partly associated with hot ionized gas. Blue corresponds to the free-free emission at the frequency of the H41α recombination line. Thermal dust emission of filaments and cores is shown in orange shades, while diffuse green features locate weak free-free emission from faint H II regions in e and f.
