If you would lose unspent mana, that mana becomes black instead. At the beginning of your first main phase, look at the top card of your library. You may reveal that card if it has three or more colored mana symbols in its mana cost. If you do, add three mana in any combination of its colors and put it into your hand. If you don't reveal it, put it into your hand.

Omnath, Locus of All (MOM-313) is a legendary Phyrexian Elemental creature from the March of the Machine expansion that carries all five colors in its identity. It converts unspent mana into black mana that persists across steps and phases while you control it, allowing future use of that mana, and its enter/trigger-like ability lets you reveal a card with three or more colored mana symbols to produce three mana in any combination of those colors when you look at the top card of your library. As a five-color commander or midrange finisher, it enables unusual mana retention and fixing strategies and can be interacted with on the stack.
