  We study the cold gas and dust properties for a sample of red star forming
galaxies called "red misfits." We collect single-dish CO observations and HI
observations from representative samples of low-redshift galaxies, as well as
our own JCMT CO observations of red misfits. We also obtain SCUBA-2 850 um
observations for a subset of these galaxies. With these data we compare the
molecular gas, total cold gas, and dust properties of red misfits against those
of their blue counterparts ("blue actives") taking non-detections into account
using a survival analysis technique. We compare these properties at fixed
position in the log SFR-log M* plane, as well as versus offset from the
star-forming main sequence. Compared to blue actives, red misfits have slightly
longer molecular gas depletion times, similar total gas depletion times,
significantly lower molecular- and total-gas mass fractions, lower
dust-to-stellar mass ratios, similar dust-to-gas ratios, and a significantly
flatter slope in the $\log M_\mathrm{mol}$-$\log M_\star$ plane. Our results
suggest that red misfits as a population are likely quenching due to a shortage
in gas supply.
