I thought this might be a useful article because I've often had a similar question. But there's a diagram that has text:
> More simply put: imagine that you have red, green, and blue light sources. What is the intensity of each one so that the resulting light matches a specific color on the spectrum?
> ...
> The CIE 1931 color space defines these RGB color matching functions. The red, green, and blue lines represent the intensity of each RGB light source:
This seems very oddly phrased to me. I would presume that what that chart is actually showing is the response for each color of cone in the human eye?
In which case it's not a question of "intensity of the light source" but more like "the visual response across different wavelengths of a otherwise uniform intensity light source"?
... fwiw, I'm not trying to be pedantic, just trying to see if I'm missing the point or not.
