I'm not even sure if this is true, because duller pictures also require blocking of light and besides, they are doing a lot of this after filming anyway (as per the article). I don't work in film, but I'm guessing most of us posting here do not. And considering that they likely already have the folks working on it and already have some lights about, the savings would be negligible. And seriously, I'm pretty sure that the CEO being colorblind doesn't matter whatsoever. They likely realize they are colorblind by now and it isn't like they are the ones filming nor making final calls on color nor other artistic stuff. In fact, I'm going to guess the CEO is more concerned with money and the pandemic and that sort of thing. I'm honestly not sure why you would bring that up. It also wouldn't explain the reasoning for, say, DC movies to be similar nor the myriad of films that aren't superhero movies to be the same.
