However, if we apply a transform to form colourimetry? The most basic principle of shape invariance is violated.
Camera colourimetry stretches and warps the quantal records to “match” know coordinates. We can end up with virtual record primaries that are negative relative wattages, all because of this ridiculous obsession with colourimetry.
Those negative relative wattages, in terms of the *integrations* of the geometric point samples of R+G+B records, will “remove energy” from the sums.

When we form a pictorial depiction of these colourimetrically formed relative wattages? Our basic spatial invariance is broken. Our “energy upon wall” gradients will tragically yield busted pictures that have *no know solutions*. All efforts of “gamut mapping” turn into charlatan games of moving coordinates around without a consideration of the goal. Yet more ill defined problems. Under a spatial invariance lensing, a reasonable goal is far more clear, and changes the framing of the problem.
