Top: color-magnitude diagrams of HD 19467B (red star) using the SPHERE narrow-band photometry. Template dwarfs (colored points) and a few young low-mass companions (indicated by black labels) are also shown for comparison. Bottom: color-magnitude diagrams of HD 19467B using the Keck and NaCo broad-band photometry. Evolutionary tracks from the COND model (Baraffe et al. 2003) and DUSTY model (Chabrier et al. 2000) for an age of 8 Gyr are also indicated with a few known T-type low-mass companions (colored points).
