Comic 49: About Rainbow Power

Rainbows, rainbows, rainbows! I have almost no time to draw... I did this comic really fast and actually rushed (And that shows!), I had the idea all of sudden and I just wanted to create it right away. Maybe my fastest produced comic ever. 
So, I like the concept of the "Rainbow Power" but I think it should have been something more neutral, you know, something that nopony of the mane six has all over her name, mane and tail and cutie mark. What's actually the point of putting rainbows on rainbow dash and what does that form? A triple rainbow? Quadruple perhaps? Anyway, maybe Sun Power, Moon Power or Light Power would have been nicer for me. I know the episode(s) will be actually good, they have to...
