Reverse commander:
Commander where the colors allowed in your deck are the colors that aren’t allowed in a normal commander deck for your commander. And your commander and their all mana symbols on them may be counted as two generic/colorless mana if your commander became colorless (if was previously all colors) or as any of the colors it now represents. I.e. Jodah, archmage eternal, now has instead of wubrg cost replacement as an ability he has 2/c 2/c 2/c 2/c 2/c as cost replacement. And he now costs 1 2/c 2/c 2/c. This color flipping will result in many commanders becoming almost useless as they have parisitic mechanics that require a specific colors mechanical allotments.
