Mew Pop 5

[Electipwner]

Mew's Copy attack says the following: Choose one of the Defending Pokemon's attacks. Mew copies that attack. This attack does nothing if Mew doesn't have the energy necessary to use that attack.

Does this mean that you must have the exact type of energy needed to use the attack or simply the right number?

Both number and color.
