I remember some colleagues at work labeling me as a blue person a few years ago. I didn't pay much attention to it, as it came from the types of people you'd expect taking this kind of bait.

I think the interesting thing here is how stuff like this spread through society. Or, parts of middle class society that is. We appear to have a large number of HR people, middle management and ambitious LinkedIn men who spend their time with things like this rather than doing actually useful work. Kind of like the class of useless people sent off on that space ship in HGTTG.
