That is interesting!
I've thought that for awhile. For example, this...

I think orange and purple have some of the same linguistic developmental history, in that, they weren't very well used until relatively recently. So orange was red or yellow 150-200 years ago and purple was blue. (I think I researched this once, but now I don't remember for sure.)
As a major color geek, I find it frustrating to be limited in my word choices for colors, so I appreciate the more accurate descriptions.
