Greetings!
I have found a bug that when you break a warped and crimson door on the bottom half the block, The breaking texture of it becomes purple and black and not it's respective color. I have also tried to break in both creative and in survival and the breaking texture is the same purple and black.
So I would be happy if this Bug was fixed in the next release 1.16.2.
-thanking you
