Err, no it doesn't?! And even if its caption *would* say it's RGB (which,
again, it doesn't), then the image itself is clearly RYB (as red, yellow, blue
are the primary colours there, and not red, green, blue).

I frankly didn't expect this to be such a controversial topic. I don't
challenge the position of both purple and violet between red and blue (when not
talking about "real colour" violet, which is beyond the blue spectre). It's
just that violet is "bluer" than purple by most definitions.

For reference, "purple":
"1. any color having components of both red and blue, such as lavender,
especially one deep in tone. /.../ 6. deep red; crimson." [1]
"b (1) : tyrian purple (2) : any of various colors that fall about midway
between red and blue in hue" [2]
"a dark reddish-blue colour" [3]
"1. A colour intermediate between red and blue. /.../ 2. A crimson dye" [4]

[3] https://dictionary.cambridge.org/dictionary/english/purple
[4] https://en.oxforddictionaries.com/definition/purple

And "violet":
"5. reddish-blue, a color at the opposite end of the visible spectrum from red,
an effect of light with a wavelength between 400 and 450 nm." [5]
"2 : any of a group of colors of reddish-blue hue, low lightness, and medium
saturation" [6]
"a bluish-purple colour" [7]
"2. A bluish-purple colour seen at the end of the spectrum opposite red." [8]

[7] https://dictionary.cambridge.org/dictionary/english/violet
[8] https://en.oxforddictionaries.com/definition/violet

Notable parts:
* both purple and violet are "reddish-blue" (which they are; however such
definition leaves much playroom and doesn't specify their position relative to
each other)
* purple is "about midway between red and blue"
* purple has also a sense of crimson
* violet is "bluish-purple" - meaning it's in the bluer part of aforementioned
"reddish-blue" space.

As far as RGB/RYB colour model is concerned, we can ignore the statement that
violet is "at the end of the spectrum opposite red" - although in a way it does
make it (much) closer (physically speaking) to blue than it is to red.

I hope this explanation helped :)

Please no-one swap the columns! :)
