Chroma Key graffiti is dope. Vimeo user Ingrid Jornet uploaded this video of a man spray painting a wall but instead of paint coming from the can, it looks like he’s spraying video of himself spraying the original black paint.

The idea is to use video software and replace a solid color with whatever video you want. There isn’t much about Jornet online — so there’s no way to tell if this is just an exercise or a final product — but it’s a technique that has potential for graffiti writers and digital artists alike.
