Question: Ammonia burns or Albino Axolotl changing color?

[4xnico]

Hello! I've noticed my Albino Axolotl has been turning red and i've heard on the internet that albinos sometimes change to a more pink/red color.
Please, is this natural, or are these ammonia burns? If they're ammonia related i'll make sure to change the water right now.

Here are some photos:

albinos don't have any skin pigmentation so the skin is quite translucent, this means any increased surface blood flow is quite noticeable giving a flushed/pink appearance, this increase in blood flow can be caused by increased exertion/movement, increased temperature, as well as issues with water parameters.

Thank you so much. I will make sure to monitor parameters and temperature to make sure everything is fine.
Again, thank you.
