    • ]]>     Ars Technica clarifies the idea that magenta isn’t a real color. The bottom line is that if magenta isn’t a real color because it doesn’t live on the electromagnetic spectrum, then neither is – say – light green a real color.

    If you look at a standard CIE chromaticity diagram, which maps wavelengths of light according to human perception, you'll note that every point along the curve corresponds to a single wavelength of light. Magenta, as it were, lies along what's commonly called the "pink-purple line" that runs across the bottom. All colors along this line do not exist as single wavelengths. But, all points inside the "color bag" above that line do not exist as single wavelengths, either.

    This is interesting. In the electromagnetic spectrum, there is no such color as magenta. Colors reside in the visible spectrum, with ultraviolet on one side and infrared on the other. Violet has the shortest wavelength, and red has the longest. Blues and greens and yellows all live between the two, but there’s nowhere for a color that is a mix of the two. Here’s another figure, with some context:
