    Gold paint if metallic (shiny) will not render correctly with full polarisation on lights and lens, back of polarisation until the gold looks acceptable under your modelling light, about half polarised might work.
    Alternatively shoot a polarised and non polarised version without moving camera or artwork and use the two images to make a composite in photoshop or similar (I use affinity). Layer the images with polarised on top then gradually erase the metallic gold area until it looks like gold. Polarisation for me always shifts white balance to a higher kelvin value.

    Do you have a wide gamut display? if not some greens may not be displaying correctly (on a normal Srgb display for example.
    Similarly if viewing thru an Srgb profile (under view menu item) your greens may be getting compressed into a smaller set of values, especially any intense light colours.

    I use small soft boxes with polarizing gel and circulation polariser on lens, the advantage of the soft boxes is the gel is far enough away from the modelling lamp not to burn thru so I can preview the polarisation. Disadvantage = big expensive sheets of polarising gel.

    is your Mac a MacBook Pro? or a Mac Pro with separate screen? either way find out what gamut your dealing with if it can output Srgb, dci-p3 or Adobe RGB.

    Hope some of this is useful. Best of luck

    Thanks so much for the help. I have a mac pro with dual 23 inch apple cinema displays. I view RGB. The the greens are hard to balance also. I will try the large soft boxes with the polarized lighting. I will also try the capturing with out and merging the 2 images.

    Have you profiled your camera with the new xrite software and do you thing that will help.

    Thanks
    Martin
