Ok I firmly believe that Aemma Arryn and Alicent Hightower were either BOTH light haired or BOTH dark haired, not one of each.
Lots of artists depict Alicent and Aemma looking very different, but I don't think so.
I doubt Viserys I Targaryen would decide to remarry, let alone to the daughter of his hand whom everyone advised him against marrying, just one year after his beloved wife died, unless he found her really attractive- or at least reminded him of Aemma in some way.
All I'm saying is, mans had a type.
