In Commander, your General's color identity defines what other cards you get to use, but what happens when you have a colorless General? Can you play any other colors of cards (WUBRG), or are you stuck playing only colorless?
1 Answer
You can only use cards with a colorless color identity with a commander that has a colorless color identity.
Rule 903 has the rules for the commander format, and the following subrules are relevant here:
903.4. The Commander variant uses color identity to determine what cards can be in a deck with a certain commander. The color identity of a card is the color or colors of any mana symbols in that card’s mana cost or rules text, plus any colors defined by its characteristic-defining abilities (see rule 604.3) or color indicator (see rule 204).
903.5. Each Commander deck is subject to the following deck construction rules.
- 903.5c A card can be included in a Commander deck only if every color in its color identity is also found in the color identity of the deck’s commander.
"Colorless" color identity means that the card has no colors in its color identity. If you tried to put a card in your deck that had any colors in its cost or rules text or indicator, then it would have a color in its color identity that is not in the commander's color identity.

3I don't know if this is worth noting, but you couldn't use cards with Devoid in a deck with a commander that has no colors in its color identity, unless those cards had no color identity themselves. Jun 5, 2016 at 19:12

I think it should be pretty clear, from the explicit mention of "colors of any mana symbols in that card's mana cost". Plus, there are multiple exceptions: cards with Deviod can't be used for one reason, Transguild Courier can't be used for another, and Elbrus, the Binding Blade isn't allowed for yet another reason.– murgatroid99 ♦Jun 5, 2016 at 19:51
