I find the idea of a "dark" light sort of confusing. I find this example a little more helpful: consider p1 p2 p3 3 shades of green-blue color and on the left, a yellow reference light, one has to add blue to the left to match the colors.

To me, the best way to think about "dark" light is that there is less light being reflected, or that whatever object I'm looking at is absorbing more colors. In order to have less light, that is where the "negative" light has to be added in (aka adding more light on the left side).

very saturated or dark colors are out of gamut b/c they can't be represented by our p1/2/3 additive color model. this image shows the closest we can get to matching colors; adding any p2 brings us farther from the left color, as does any change to p1 and p3.
