The group was later found to be physically homogeneous , all satellites displaying `` light-red '' colour ( colour indices B − V = 0.91 and V − R = 0.48 ) Remarkably , recent observations revealed that the largest member of the group , Albiorix , displays actually two different colours : one compatible with Erriapus and Tarvos , and another less red .
