This GIF Is The Perfect Visual Representation Of Just How CMYK Works
CMYK is perfectly represented with this GIF. The original painting was Vermeer's "Girl with a Pearl Earring" that I am sure you've seen before. I couldn't find a video but this will do just fine.
I've seen this quite a few times and like a bug to a light, I just can't resist myself.
This has been floating around FB today and you can find the original video posted on the @physicsfun instagram page!
