I presume the "cyan" axolotl in Minecraft is supposed to be an albino, however it doesn't tick all the boxes.

I've seen a few attempt at an albino skin on this platform but pretty much everybody is forgetting the red eyes that albino animals have, as well as the very red/pink gills.

Albinism is the complete lack of any pigment, this affects everything including the eyes.
The red colour comes from the cells and blood vessels under the skin or eyes.

The gills have A LOT of blood vessels as that's literally how they resperate (the exchange of gases, oxygen in CO2 out), that's why they're such a deep pink colour.

The more grey colours on the tail is supposed to represent the translucency that it has, you can partially see through the edges and the belly is slightly more grey/blue coloured because of it's internal organs.

Overall, real life albino axolotls are a bit more pink in colour, because of the blood underneath their thin skin. However I made the texture more white to be more distinct from the Leucisitc axolotl. So there is a wee bit of artistic liberty.
