Broadband colours, (u − g)o (top) and (g − z)SDSS, o (bottom), plotted against metallicity for our GC sample. For (g − z)SDSS, o, the spectroscopically calibrated CMRs from Peng et al. (2006, dotted), Sinnott et al. (2010, dashed), and Usher et al. (2012, solid) are also plotted. For both colours, the GCs below the metallicity do not separate clearly from other GCs.
