Deerling do change color in a way, but it's the form.
Deerling change their form according to the season in the game.
Deerling have four forms:
Autumn, Spring, Summer, and Winter, each one corresponding to the season in game.

The seasons change every month in game, hope this helps! ~

What do you mean "caught" deerling ... Ofcourse it changes colour that's the main feature...

A caught Deerling will retain its previous seasonal form on the first play session in a new season.  This is because the game recognizes the season from you last save state and then updates after everything is loaded.  Saving again and resetting the game will change the caught Deerling's form to the correct season.
