One night I couldn't sleep and while awake I had a realisation. Uru means diamond and there must be a reason why you could call a lioness diamond and not just cos of a marking.
They never said her fur colour in the books Then it hit me. What colour are diamonds normally?
White C;
And before people ask : Scar most likely got his red fur carried down from a either ahadi or uru or even the grandparents. A white lion parent wont give birth to a white cub unless the other parent has the white gene too.So Ahadi may not of had the white gene and it resulted in 'normal' coloured cubs. Just because uru is white doesn't mean before the white gene kicked in the red gene got lost. She could still carry it from her parents or even Ahadi could of.
