Apologies, my attention diverted to … SQUIRREL!!!
…
Sorry, back again. Okay, here’s R3:
I made a profile icon from a ppmcie graphic. Note that the Maxwell gamut triangle gets smaller as the workflow progresses, in the manner a camera → working -output color migration would happen in practice. Not sure what to say about that on the chart; in my mind, that’d be described in the accompanying prose.
I do intend to make something of this, but my attention span will be a bit fragmented in the next couple of months
