You can use any color for BG but make sure it does not appear on the subject.

Have him dye his hair or you should get ready to rotoscope a lot of frames; I suggest stocking up on Red Bull if you choose the latter.

Keying on green is highly preferred for a few reasons: digital sensors are more sensitive to green thanks to the bayer pattern (you end up with better edge detail in the green channel), and it’s also one of the colors furthest away from the hue family that makes up all human skintones.

The alternate suggestion would be keying with magenta, but I think you’d be hard pressed to find a backdrop or paint that is pure in hue enough to get the job done.

Rosco florescent pink is the only paint color I think may be near appropriate, but I have a feeling it is not indigo enough to fully protect skintones. Quarts are extremely expensive too.

I like Angelo’s suggestion of having your friend dye his hair the best. I’d keep one side of his hair blue and dye the other red. This should make it fairly trivial to change the red hair to look green in AE if your friend really wants the green/blue look. It will be much harder to find a color you can key green & blue hair & mostly red skin against.

Thanks for the thoughts guys.

The blue/green combo is kind of his thing, he’s been doing it for years, so dying it isn’t really an option.

I’ll do a few tests with some magenta fabric, and if I can’t get that to work I may abandon the chroma key idea and just stick to a traditional shoot.

Thanks again

Ah, that’s pretty ingenious, a double key. Didn’t cross my mind.
