Available photometric studies add further credibility to the common origin thesis: three of the moons of the family ([[Harpalyke (moon)|Harpalyke]], [[Praxidike (moon)|Praxidike]] and [[Iocaste (moon)|Iocaste]]) display similar grey colours (average [[color index|colour indices]]: B−V = 0.77 and V−R = 0.42) while Ananke itself is on the boundary between grey and light red.<ref name=Grav2003>
