This is simply hue and situration changes. 1st you put a black background, 2. open image url as a layer, go change the hue and saturation, and your pretty much done. Except there is no situration, just hue. This so simple to do, while if you do it my way, I first do hue and saturation first to get an idea then recolor them the way that hue did, so Im not technically cheating. Nice "recolors" though.
