I'm partially red green colorblind and when I first saw this image, it was definitively white/ gold for me. Then after researching a couple websites I saw the comparisons and such, and was able to see how it could be perceived as blue/ black. NOW whenever I look at it, I can ONLY really see blue/ black ( I wonder if this is because I have now seen the picture confirming it's blue/ black nature?). I also wonder if through compression from reposting etc if the rgb values may have been changed ( or people have tampered to prove their side).
Quite a weird conundrum on color and perception to say the least.
