I'd like to create a toolbar of buttons that will change the fill color of PPT objects (instead of clicking on the Fill button and selecting a color, the color buttons would be directly on the toolbar... it would look kind of like Microsoft Paint).

My approach is to create a custom toolbar with each button assigned to a macro that sets the fill color to the color shown on the button. I have the code all ready to go as long as the colors are fixed, but I can't find appropriate Face IDs for the buttons. Ideally, I'd like just a simple colored square for each color like the existing Fill toolbar has. Any way to make a button look like that?

I'm also not sure how to allow the user to re-assign colors... which is not totally necessary but definitely nice to have. Is there a better way to do this than what I've described above (that would let the user change the button colors)?

Thank you!
