I tried that video experiment several times and if I was supposed to see a color photo when it went to black and white, then I failed. Then again,
maybe I am not really able to focus on something as small as that black dot to the exclusion of the rest of the image. I've trained for years to see
everything within my field of vision equally (a survival skill that I needed for a while - long story) and while it's very useful for driving and
whatever, it's harder to pinpoint my vision for any real length of time.
As far as color being 100% human perception, the fact that a humming bird is attracted to red flowers suggests that color does exist and is part of
the survival suite that all of nature employs. Then, there is the fact that I can replicate 0, 255, 0, blue accurately every single time I try, and
anyone else can too if given the proper recipe. This definitely suggests that your philosophical house guest is toying with you, and using freshman
year material to do so.
There are philosophical conundrums that exist, but the "is color real or the product of perception" question isn't one of them. The question of
whether my blue is the same as your blue, and whether that can ever be determined is not the same question of whether blue itself actually exists.
Blue does exist. We've even stabilized it as a definitive base color and established a hue gradient for it. That means that, yes, it does exist
regardless of what you perceive it to be.
