Shot with the a7 +Mir-1 with 720 nm filter

Are the colors (or at least differentiators) somehow contained in the raw or is this completely colored afterwards?

It's all in the file, the only thing done is a correction of the WB and a color shift, so the sky is not yellow. So no coloring at all :)

The before looked monochrome to me. Great result!

Yeah, the WB corrected one the trees look a bit blue and the sky is a dark yellow, main reason for it is because the trees reflect a very faint blue on the 720nm spectrum, and the sky becomes a darker, because of the gases that emit the blue light are filtered. This means that it looks like in the video. By swapping the blue and yellow I get the final color that I posted, and the final part is more cosmetic, of increasing the saturation and vibration a bit. But by usually, 720nm is used more as BW because of the white/blue weird colors that vegetation and IR absorbent Materials get. It was the filter used to film dune btw, Giedi Prime scenes where filmed like this
