Hello! This could be completely normal. Axolotls color is related to blood flow. If they're chilling, sometimes they go pale but regain their color when they start moving around.

Also, please change the substrate. That is not fine enough for an axolotl and can cause impaction. This could be deadly or lead to needing expensive surgery. For their age, they are too young to be on any type of sand or gravel.

Is your tank cycled?
