You see how fighting games have these meters? The Rasengan would cost 1 bar, and the Kamehameha would cost 4 bars. Because TLX didn't quite have enough for that one, she used something in-between. The levels so far seem to be Blue, Dark-Blue, Purple, and Dark-Purple. Those closer to Blue behave like a grenade, and those closer to Purple behave like a beam.
