The colour correction seen on earlier videos and the ESB reconstruction was just the first phase of correction. I had to strip the cyan out of the picture to be able to have a start basis to be able to restore lost colours due to their heavy handed colour filtering. This in turn cause blues/ cyans that should have been there to be lost and had to be restored at a later date. The rescue scene was always blue and Dagobah was also blue tinted. Puggo's ESB is the closest you are going to see of the correct colouring for ESB unless they do a proper restoration of the film. ESB was never completely blue like the DVD's/ Blu-rays but you would be surprised just how much blue was in the picture. My goal was always to restore it close to how it originally looked. It won't be be exactly the same though as there is only so much you can do with the source used.

oh, and ignore the saturation of the latest ESB:R screenshots. I have no idea what happened but when capturing them to png the saturation was boosted, especially in the reds. I'll try and recapture some so you can hopefully see the true colouring

I'll also reply to some of the other comments as son as i can
