We report the discovery of three planetary-mass companions (M = 6--20$M_{Jup}$) in wide orbits ($\rho \sim$ 150--300 AU) around the young stars FWTau (Taurus-Auriga), ROXs 12 (Ophiuchus), and ROXs 42B (Ophiuchus). All threewide planetary-mass companions ("PMCs") were reported as candidate companionsin previous binary survey programs, but then were neglected for $>$10 years. Wetherefore obtained followup observations which demonstrate that each candidateis comoving with its host star. Based on the absolute $M_{K'}$ magnitudes, weinfer masses (from hot-start evolutionary models) and projected separations of10 $\pm$ 4 $M_{Jup}$ and 330 $\pm$ 30 AU for FW Tau b, 16 $\pm$ 4 $M_{Jup}$ and210 $\pm$ 20 AU for ROXs 12 b, and 10 $\pm$ 4 $M_{Jup}$ and 140 $\pm$ 10 AU forROXs 42B b. We also present similar observations for ten other candidates whichshow that they are unassociated field stars, as well as multicolor JHK'L'near-infrared photometry for our new PMCs and for five previously-identifiedsubstellar or planetary-mass companions. The NIR photometry for our sample ofeight known and new companions generally parallels the properties offree-floating low-mass brown dwarfs in these star-forming regions. However, 5of the 7 objects with M $<$ 30 $M_{Jup}$ are redder in K'-L' than thedistribution of young free-floating counterparts of similar J-K'. We speculatethat this distinction could indicate a structural difference incircum-planetary disks, perhaps tied to higher disk mass since at least two ofthe objects in our sample are known to be accreting more vigorously thantypical free-floating counterparts.
