I don't know, but I can offer paintings like this, by Pixelpchan.
Also Tonko House for a studio that has this distinguished style of using saturation.
Nothing as wild as yours, it plays a lot with contrast and saturation.
Sometimes when I'm painting I play around with filters for finding new color ideas and stuff like this happens, I'm assuming it's not painted like this from the get-go. If it is, that's interesting, I might attempt this one of these days.
