Nice! Any chance to see the original one with colours?

This may be from an IR sensor.

Fun Fact: Basically all sensors are IR sensors, but most have a IR/UV cut filter that keeps it from getting through.

IR stand for Infrared, a regime of the light spectrum which lies outside the visible regime. So there aren't any colors; the different IR wavelengths here are represented in grayscale.

It depends on how the image was captured. I have a camera I converted to "full spectrum" by removing the IR/UV cut filter. It can still collect visible light, no problem, and you can use various filters to utilize whatever wavelengths you want.

That said, given the amount of noise, this looks like something that was taken with a standard camera and a long exposure through something like a Hoya R72 so there probably isn't a color version in this instance unless OP took a separate one.

Thanks. as the others mentioned this was taken in infrared so it didn’t capture colors. This was taken with a Sony F828 which can shoot IR by tapping a magnet on the side of the lens. I have a IR850 filter on it to limit it further. I did edit it in snapseed to take it from a purple tone to b&w.
