Panda's Tail: Black or White？

What color do you think the panda's tail is?
Black or White?

When I was watching a TV variety show featuring giant pandas, a narrator of the show asked the audience such kind of question.
I assumed it was black, from the color of their ears and legs.

But I guessed wrong.
The answer was "white."
The narrator added an interesting story about the color of the panda's tail.

It was in 1972 that a pair of giant pandas first came to Japan.
They were named Kang Kang and Lan Lan.
It is said that the two pandas were donated from China to commemorate the normalization of diplomatic relations between the two countries.
At that time, for most of the Japanese, pandas were unfamiliar animals.
They were so lovely that they soon became popular among people of all ages.
Various kinds of pandas-related goods began to be sold, such as stuffed animals, toys, and stationeries.
At that time, pandas were rare animals and toy manufacturers had to make those things from photographs of them, in which pandas faced the front.
The companies couldn't see their tails.

They supposed that pandas' tails were black.
So the tails of stuffed pandas and toys produced at that time were black.

I remembered I still keep a coin bank in the shape of a panda, which a friend of mine gave me on my birthday, when I was a child.
I looked at its tail and found it was "black !"

It's interesting to know that there was little information about pandas in those days.
They were so rare animals for the Japanese.
