A few days ago I was asked on Quora if I could explain why Barney, the talking dinosaur from the kid’s TV show, is described as being “purple”. I prepared the graphic below as my response. Possibly a bit over-the-top, but, hey, I sympathize with anyone who has a difficult time accepting that Barney is “purple”. Probably because I grew up in the upper midwest and thus for me the color “purple” was that found on the uniform of the Minnesota Vikings. The “purple” found in most colors wheels is also considerably bluer than Barney. However, his coloration is consistent – or, at least, not inconsistent – with the older tradition of “purple” being inclined much more toward red.
