Hey there, welcome to the .org
This effect seems actually rather easy to make, though will require some work.
First, you need to mask each part of the character you want to appear alone. (face, legs, body...whatever you want to appear with different color)
Then you simply add a color event (orange picture for example) in a new layer and copy the mask from your footage on that event. Your mask will then appear on the colorevent and you have for example an orange leg. (once you removed the actual scene)
I don't think I'm good at explaining such things, but I hope you understood anyway.
Feel free to ask again if there's something unclear.
