I actually get asked this a lot. The short answer is that Rainbow Energy doesn't discriminate about what type it is.
The longer explanation is that while attached to a Pokemon, Rainbow Energy counts as every type of energy all at once, but only provides one "unit" of energy at a time. It's type never changes to whatever its owner wants- it just counts as everything all of the time. That said, it's subject to anything that targets a specific type. This is also why if you use an attack that requires you to discard a specific type of energy, like Dialga-EX's Full Metal Impact, if the only cards providing Metal energy are Rainbow Energy, then you have to discard them. You can't simply say they're no longer providing Metal after you declare the attack and not discard. That would be broken. xD
