Spectra, blue region from 4200 to 5800 Å, of KDM 5651 and a selection of 11 newly discovered Galactic Cold RCB stars that present the best signal-to-noise ratio. The underlying blackbody curves were removed. The large C₂ band-heads features (2,0), (1,0), (0,0) and (0,1) are clearly visible. We plotted them in order of the Ca II IR triplet strength, from stronger to weaker lines (top to bottom), that is, in decreasing order of T_eff. The spectra were smoothed (5 points were used) for a better presentation and comparison. The names of the corresponding stars are given on the right side.
