   \caption{\label{colmag_conclusions}Fraction of blue galaxies. In the case of CL0056.03 a galaxy is 
defined to be "blue'' if $V-R<0.755$, i.e., if it lies more than~$2\sigma$ below the cluster sequence 
$V-R=0.795\pm0.02$, as defined by galaxies with $R<19$. Galaxies with $V-R>0.87$ are exluded from the 
statistics. For CL0056.02 the~$2\sigma$-threshold for "blue'' galaxies is $V-R<0.79$. Galaxies with 
$V-R>0.85$ are excluded from the statistics. Note that the number of interlopers is reduced in the 
outer two annuli since they are significantly truncated by the edge of the field of view.}
