I'm not assuming. I can see your script with your name on it, Andrew.
I'm going to take advice from the IT specialist on that site before I take advice from a Color Management Consultant.
It isn't my script. Just like I didn't process any image here, of mustard bottles or anything else.
You don't take advise from color management experts so I can't fathom you'd find then take advise from an IT specialist either.
All I did was copy and paste a URL from a site I can navigate to, as the screen capture proves. Don't go there, it is likely over your head anyway. Start with JP's piece, then Jims, see if can connect the dots such you begin to understand
issues with color matching and illuminants. Or don't.
