[AccessD] Tab Control Hover Color Changing

I created a new form, added a 3 page tab, changed the Use Theme property to no, changed the Style to buttons.
Viewing the form provided no hover fore color.
I added a button which set the hover fore color in code. The buttons now have a hover color but it is the same pale blue (not the red I set it to).
It seems that any vba manipulation of the tab control causes a hover color to appear (but not one that can be changed) ☹

There are properties of the tab control which are "not surfaced in the property sheet". Meaning they exist and can be manipulated but you can't see them in the property sheet. Have you played with all these things?
The explanations on this page frankly suck.
