Just to ask, if I have a colorless commander I can use any type of mana , but I will only produce colorless mana right.
Yes, but you can't include most lands. You need colorless mana producers because anything that produces black mana has a color identity of black, same with each other color. This is part of the reason colorless decks see almost no play, because the mana base is such a pain.
However, anything that says "produce mana of any color", or anything that doesn't specify any colors (
City of Brass and
Exotic Orchid, for example) is fair game.
