If a manufacturer makes a reader with a green light option he's going to need a different way to market it.

Saturated colors are not very common in nature, but LEDs are among the spectrally narrowest light sources around and LED is the cheapest and easiest light source for a hypothetical green light ereader. Using pure green illumination is not a technical or economic problem.
I'm not sure what you are trying to say about the ordering of the colors in
https://htmlcolorcodes.com/
or what that order or distance along it has to do with anything, but its definition of green is:
GREEN #008000 RGB(0, 128, 0)
which has no red and no blue. Green is well, green, as is the light from a green LED.
