Full black colored tigers don't exist however black striped tigers do exist.

There are reports of pure black non-striped tigers (true melanistic tigers).
Most black mammals are due to the non-agouti mutation.
Pseudo-melanistic tigers exist and can be seen in the wild and in zoos.
Such tigers are said to be getting more common due to inbreeding.
Golden Tigers are rare and the population of the Golden Tiger is decreasing.
Golden Tigers are considered endangered and they may not exist in 50 or 100 years from now.
While Royal Bengal Tiger is in itself an endangered species in India, this Golden Tiger is the only one of its kind recorded in the wild in the entire world, in the 21st century.
Although Golden Tigers are found in zoos across the world, this is the first time that they have been spotted in the wild.
The Golden Tabby tiger is one of the world's rarest big cats.
