Why are lab rats typically albinos?

This may be a silly question but I'm not a geneticist, and I'm curious why animals used as test subjects in media - particularly mice, rats, rabbits, etc. - are almost always depicted as albinos.

TLDR: it makes things easy

Lab rats are typically albino due to the fact that these lot easier to work on and see results of an experiment when the rat itself has no pigment to block out any physical characteristics that may exhibit when testing. For example it is a lot easier to see skin change when it is stark white and it is a lot easier to see veins to inject stuff in so a lot of animals that are used in Laboratory Testing are breeded with albinism not just rats.
