If I change the background of a Trello board, does it change it for the entire team, or just for me?

I'm unable to determine whether background changes are personalizations unique to the team member who makes the change, or whether every team member sees the same background, no matter what it gets changed to, no matter who changes it.

From the trello help:

Once you've changed the board background, all other users that view that board will also see that same background. 

So, yes it is for the entire team.

Thank you.
