actually, the effect was done by first creating a design with the brush tool, then distort wave, then fade, and distort again, then outer glow, then duplicate, then color, then set the duplicate to screen, and distort wave the duplicate, then offset it to the left, then merged them together, then used the dogde tool, to highlight some areas, then duplicate again, then put a motion blur on that duplicate, then set that layer to difference. and i think its a nice transition of color from the right to left, or even left to right. its just yellow, orange, red orange, red and green. and thats the colors that are in the render.
