It's a palette of predefined colors. It's been used by the printing industry for many years, everyone who does any kind of professional graphic arts knows what it is. You can just tell the press operator "give me Pantone 68C" and they will know exactly what to give you. https://www.pantone.com/ https://www.pantone.com/

Also missing is: what is a "color"? It might sound like a stupid question, but once you start thinking about it, it's not so simple. For example if you take a color and change the intensity of the light by a factor 2, is it the same color? Also due to overlapping spectra of cones in the human retina, different spectra can generate the same perception of color. Et cetera.

  I'd assume that with something like intensity that as long as the "ratios" of "RGB" values so to speak stay the same, your brain would interpret it as the same color, but that's my thought!

    Probably not true. Different shades of gray have (more or less) the same RGB ratios, but there exists a wide variety of PANTONE numbers for different shades of gray. (Simply put).

  In typical technical contexts, 'color' usually gets it's meaning from CIE 1931 or a derivative of it. The science of human color perception is colorimetry. Photometry is the science of human perception of brightness. Philosophical skepticism deals with the shortcomings of this approach. https://en.wikipedia.org/wiki/CIE_1931_color_space https://en.wikipedia.org/wiki/CIE_1931_color_space https://en.wikipedia.org/wiki/Colorimetry https://en.wikipedia.org/wiki/Colorimetry https://en.wikipedia.org/wiki/Photometry_(optics) https://en.wikipedia.org/wiki/Photometry_(optics) https://en.wikipedia.org/wiki/Philosophical_skepticism https://en.wikipedia.org/wiki/Philosophical_skepticism

  It's not the same color, no. Brown doesn't exist. Check out https://www.youtube.com/watch?v=wh4aWZRtTwU https://www.youtube.com/watch?v=wh4aWZRtTwU

  Oh boy, I spend like 3 months researching the scientific and objective background behind what color and light is. I suggest reading this: http://graphics.stanford.edu/courses/cs148-10-summer/docs/2010--kerr--cie_xyz.pdf http://graphics.stanford.edu/courses/cs148-10-summer/docs/20... Extremely excellent resource. I was gonna write a blog post summarizing my adventure until I found this. Basically what I was trying to write.

The palette is possible because of proprietary non-CYM(K) ink(s). What distinguishes the Pantone print colors is they are outside the CYM gamut. With web colors that's not the case, but by the time the web came around Pantone had established its value as a commercial service in support of color critical work.
