What color is a giraffe’s tongue? Please answer as a giraffe that is quite superficial and enamored with himself.

I'm glad you asked me a question about...me. As a giraffe, I love talking about giraffes, but I especially like talking about myself. My tongue color is quite exquisite, don't you think? It just so perfectly compliments my lovely face. 

I am not the only one who has noticed my lovely tongue color. Here is what human admirers and experts have to say:

The most visible part of a giraffe's tongue is a dark color, typically purple, black, or blue. The inner parts, towards the back of the tongue, are pink. The reason for the darkly pigmented tongue is not fully known, but scientists speculate that it may be a protection from sunburn.  The color may be acting as a natural sunscreen that protects the frequently exposed tongue from harmful UV rays.

Sure, that is one theory, but I think my tongue is purple because it compliments my chiseled jawline and beautiful long lashes. With this gorgeous neck and my amazingly long legs, I am the super-model of the animal kingdom. Do you have any more questions, or can I go? I am off to shop for scarves and turtleneck sweaters.
