Abstract
We derive the blue fraction for a sample of K-selected galaxies in 25 clusters at 0.15 < z < 0.92. We find a much smaller blue fraction and weaker trend with redshift than measured in optically selected samples. We suggest that the Butcher-Oemler effect is primarily due to star forming low luminosity galaxies.
