[Saraphim]

I do not doubt that the hare, upon the time of its birth, was white.

But Legolas, after experimenting with different colors for his own head at an early age and finding that it only made his beutiful locks brittle and lackluster, would have recieved the rabbit and then proceeded to dye it whatever color the esteemed elven princling had an urge for.

At the time of the War, it was obviously purple, as Legolas would have wanted his hare to be his favorite color to comfort his thoughts on the long nights he spent in travel.
