Distribution of NGC 2264 members on a gr vs. ri diagram, built using the SDSS-calibrated photometry obtained for the cluster with CFHT/MegaCam (Venuti et al. 2014). The green line shows the empirical, zero-reddening SpT–color stellar locus derived in the statistical study of Covey et al. (2007), recalibrated onto CFHT photometry as in Venuti et al. (2014). The reddening vector is traced following Fiorucci & Munari (2003).
