The intracluster light(ICL) is a product of galaxy disruption that can be used to trace the physical processes at work on galaxy evolution in clusters. To better understand these processes, we are undertaking a survey of the flux, color and substructure of the ICL in ten clusters which are representative of a wide range in cluster characteristics such as morphology, richness, redshift, and mass. With the first cluster in our sample we have shown the ability to measure a diffuse ICL in clusters with accuracies of ~ 28.8 mag arcsec-2 in both V and gunn-r (<1% of the sky brightness). We also measure a V-r color and substructure in the form of tidal tails and wakes which allow us to place constraints on the origin of the ICL. We present here the higher redshift portion of our sample (0.15 < z < 0.31) for which we have similar quality data.
