Actually that last response came across I made as quite blunt. If it's everywhere else feel free to tag this as rejected. @Mike I just thought @mutedTextColor would have been much clearer and is widely used but no biggie.
I don't think I've been using pages in the admin side where this text colour shows. I look around and noticed Customized style components page (text) is using it but I never needed to view or go into this area so never noticed it before. Since I was more likely to use the TM it's the first time I've noticed it.
