This is a stupid question, I'm 99% sure I'm right but you never know. Help settle a dispute.
Rogue's Passage - tapping this only produces colorless mana, right? You could not use this card to activate something with say, a 1 green mana cost.
It is only good for the colorless aspect of a cost, like in 1RR - this can only be used for the "1 colorless" part of the cost, not either of the red cost.
My son swears it is like a wildcard mana card, "can be any color", whereas I say it's just for the colorless part.
You're correct. There's no such thing as wildcard mana. Compare the wording on Rogue's Passage to Mana Confluence. The latter can make any color, but you still have to make a choice when you tap it. (So, sort of wildcard, but if you pick green and then later want to use red, you're out of luck).

Colorless mana is a type of mana which is not any color, so it can't be an appropriate color for any of WUBR or G.
