Green and blue are canonical because they tend to have strong contrast with the people and their clothes, so the cromakey isn’t likely to pick up random bits of people’s face and outfit to cut out. If you want to go for the green cardboard option I would just make sure you get as consistent a color as possible and see about finding a cheap light and/or reflector to put behind you so that it doesn’t get obscured by your shadow. Definitely had that happen in a couple of student projects I did and it was impossible to set it up to be an aggressive enough match to always get the board (including the shadowed parts) without also picking up the lining of someone’s jacket or something.
I feel like he’s also broadly misunderstood the actual armchair diagnosis from over here. Like, no acknowledgement of claims that he’s stuck in a broken and obviously false framing of the entire world as “popular jocks” vs “put-up on nerds” and seems to match literally any conflict into that model to often horrifying results. Even though that was the main thrust of the actual “diagnosis” that he referenced.
Past a certain point I think anyone who doesn’t agree with and support him has been fully excluded from the circle of people who can actually get through to him and help. Unfortunately, he’s still a public figure, leaving the rest of us with little to do beyond sneering.
