I read a detailed interview with the person who does the enhancements a couple of days ago (can’t recall where a grrr).

He said: A) there are two of them in the team doing the imaging B) it doesn’t start with an image - it’s literally heaps of binary data that the scientists stitch together C) he then does the colour overlay based on agreed norms (one colour per input frequency for consistency) D) most of his “touch up” work is getting the colour gradient right between the brightest and dimmer objects - without this a lot of resolution would be lost (brights too bright, or dim not visible).

Hope this helps…
