Left: color-magnitude diagram considering the SPHERE/IRDIS K1 photometry, and the J_IFS photometry from 1.2 to 1.32 μm as it can be extracted from the SPHERE/IFS datacubes. Right: color-magnitude diagram considering the SPHERE/IRDIS K1 and K1 photometry. In both cases, Measurements of M, L, T field dwarfs, and of young companions and red dwarfs are reported. The reddening vector computed for the synthetic interstellar extinction curve for a 0.5 mag K band extinction and reddening parameter of R_v = 3.1 is overlaid (black arrow). We also report the reddening vector from the extinction curve of forsterite dust grains with size distribution centered on radii r = 0.5 μm and for a 0.15 mag K band extinction (light blue arrow). As proposed by Marocco et al. (2014) and Bonnefoy et al. (2016), both could explain the deviation of the colors of young and dusty L6–L8 dwrafs, and of the HR 8799 planets with respect to the sequence of field dwarfs. The photometry of HD 95086 b shown by the blue cross with uncertainties in both diagrams is characteristic of young L/T transition objects.
