Recovery : Fujifilm 120mm Colour Film

Recently, I had found this old developed film from my old box, which I left them for a quiet long time. The color is faded away, a few dust and dent. I got no time to print this film. This is Fujifilm Pro 120mm Colour film used by Holga CFN120 at Melaka on mid-2012.

So I decide to warm them with my scanner. Luckily, the image still there. So I took few moment for editing and recovery process, yet, I only able to recover them in B/W. Because the color is totally faded away. 

My final image on B/W, I want to make them in color, but it's hard to recover them. I do inverse and use all channel to fix the color, but the sky is red and too many grain and noise. Hope some help me.
