We present the analysis of the color-magnitude relation (CMR) for a sample of 57 X-ray-detected Abell clusters within the redshift interval 0.02 less than or equal to z less than or equal to 0.18. We use the B - R versus R color-magnitude plane to establish that the CMR is present in all our low-red...
