If there's any hope of this happening, my boss would be very happy.

@punker76 How do you want to proceed for this ticket? Shall I copy-paste the MUI brushes and styles for default component as-is (for example create new files called Dark.Mui and Light.Mui) or shall I try to adapt them to use the same color keys as what we have for Amber and so on?

@Evangelink I am definitely not @punker76, but I think that color keys across styles should be consistent, especially for those of us who create & implement custom themes and/or accent colors. It would be more work up front, but makes life easier for developers in the long run. This would also go a long way when it comes to implementing items such as #3563, as colors would sty consistent across switched themes.
