Not so much wouldn’t as can’t. I wasn’t able to find the source paper, but it sounds like they used a very narrow wavelength so that they only stimulated certain cells. Outside the lab, light emissions and reflections aren’t so narrow.
It’s not just the narrow wavelength. Even with a perfectly monochromatic green light, your green receptors would activate a lot but your receptors for red and blue would still activate a bit. These researchers specifically target only the green receptors to activate (by literally shooting light at those receptors in particular), so for the first time ever your brain reads a pure green signal.

Far point on “can’t”.
On the source paper, I found it - it was initially published in science.org.
