From your link, compare the red RBG bar to the clearly orange bars at the side of the screen. Additionally the 'Analogous Colors' contains an even more obvious orange, and pink, but no sign of red.
Arguing about this over the internet is somewhat comical, as you are probably being represented by your computers at least slightly differing colors, and at most entirely different colors, due to things like screen quality, viewing angle (if LCD), brightness/contrast settings, etc. Trying to use specific descriptions are can be replicated by a computer is a good step, but ultimately of little use if you can't be sure that same color is represented the same to who you are talking to.
I mean, obviously, the color is blue. Or is it gold? In any case, it's definitely a dress...
Display technology also varies quite a bit. Some cheaper devices tend to saturate certain hues like redness. It could very well look a bit more orange on one display and look completely yellow on another.
