Harmy, i'm not seeing Han's red eyes on my screen to be honest. Maybe we're using different renderers? I've heard that that can sometimes cause changes in colours. I'm using the 'mpc video decoder' filter with 'video mixing renderer 9 (renderless)' output on media player classic. As for palette, mine is just exactly the same as the blu-ray, albeit with the blue tint removed, nothing more, nothing less.
Here are two screencaps using PrtSc on media player classic, one from the blu-ray itself and one from the video I posted just now, which is essentially the blu-ray stream regraded to remove the blue tint but leaving the rest of the image dynamics like brightness/gamma/contrast/saturation pretty much the same.

And here's the screencap from my clip you posted before as it looks on my screen. Han's iris is slightly red if you look very closely but apart from that I don't see much red in his eyes to be honest:

I personally see the cyan in the shadows and blacks of the screencaps you've posted up there on the right, especially on the boots. You_Too seems to see it too. Anyway, regardless on how you decide to proceed, you have my full support. This is your project and I'm really looking forward to seeing this finished, so don't mind me and my silly nitpicking! :)
