That is a really cool fact however I found the article to be slightly misleading. Magenta is not a real colour in the sense that there is no single wavelength associated with it however it is not visual illusion either. Their exists magenta pigment and paint that you can buy that reliably reproduces the same color. Magenta is your brain interpreting seeing high intensity of red and blue together.
Fun fact: magenta is not a real color.
