Why does my Default Color change (and how to change back?)

Somewhere along the way I changed my “Default Color” from the standard default to a specific color in my palette. How do I change the default color back?

Edit it in Styles.

@DaveR always appreciate your help - I looked 3x and I can’t seem to locate it. Little help please sir.

Please fix your profile. It’s still confusing.
