I'm unable to change my Terminal app profile (color theme) even when I change it in the preferences. I selected Homebrew as my profile, closed Terminal and reopened it - but it won't actually change to Homebrew. It shows the basic (default) profile.
Is it possible that I have an issue with my .bash_profile, .bashrc, or .profile?
I'm trying to change it to the profile "Homebrew" seen below:

Solution:
The solution was to change the "Homebrew" profile to default (this can be undone later).
Go to Terminal preferences (Command+,), then select the "Profiles" tab, and then highlight "Homebrew" and select the "Default" button near the bottom left of the window.
Then close all Terminal app windows and quit Terminal.
Upon opening again, it should show the "Homebrew" profile theme in a new window.
You can change the default back to any other profile.
