A land is normally colorless, regardless of what colors of mana that land can produce. If an effect makes a colorless land into a creature without specifying that it becomes a certain color, the land creature gets +2/+2.

You “tap a permanent for C” only if you activate a mana ability of that permanent that includes the T symbol in its cost, and only if it produces one or more C as it resolves.

If you tap a permanent for more than one C, you add only one additional C.
