For a special celebration, my parents, with very good intention but poor knowlegde, knowing my increasing taste for collecting animal replicas, gave me as gift a realistic white tiger.
I just felt very happy once they told me that I can change the figure in the same shop that was bought. I go here the next day and changed the tiger by my current sperm whale.
I also avoid photographing them for mi gigantic archive of own-made biodiversity photos. I rarely even kept more than few seconds looking at them in zoos, pet shops or whatever. I must have a photo of every species possible, but I still not have any photo of Ovis aries, Capra hircus or Cavia porcellus just because I never found ones with natural-looking coat for photograph.
There are some exceptions - I keep orange goldfishes in my pond just because natural ones are too difficult to get - but I usually avoid anything related with artificial man-made live animals. Same applies for the plants I grow in my garden.
These are just my personal tastes only. Of course others can find mutants very appealing - if not, CollectA would not make white lions!
