Thanks Chris - what sort of PP would u do for it in Colour?
I would need to see the colour to judge this properly.
The colour balance would be the first problem.
You'd most likely have to warm it up the right amount.
For that I'd temporarily boost saturation very strong and then check at which color balance and tint I get good colour separation.
Then I'd pull down saturation again.
Then I'd experiment with saturation boost or reduction, maybe selectively only on parts of the image.
Also selective changes of lightness or hue might get you further.
But that all depends a lot on the colour palette in the image and what it offers.
Lost of room to play here.
