Out of gamut refers to the fact that the test light is out of the range of the possible colors that can be formed by the primary lights. We can remedy this by shining a primary light onto the test color's side such that we are no longer out of gamut. We say a "negative" amount of p2 w3as needed to make the match when doing so, and while "negative" light is not really possible, representing this as negative is useful when it comes to linear equations that describe colors

Kind of confused about why you can be out of gamut instead of just adding more p1 and p3? Is it a physical limitation of the lights or something else

RGB values are always negative, but why there is a negative spectral function here? Could anyone explain please
