Look at the Hubble pics for Ha, S2 & O3 filters.
Ha is much brighter than the other 2 but they normalise it
to make an interesting picture and it shows which elements are shining
and where they are and their relevant structures.
Well, following on from what I stated earlier, when you add colours that are not even part of the human visual spectrum to an image you can certainly generate some striking imagery.

...but that's the rub....it's "imagery" and not a view we'd see with a warm human eye.

And it can be fun highlighting a particular ionization region etc. The downside is many think the view is "real"....i.e that's what you see staring out of the bridge of the Starship Enterprise.

Fun sure. Colours of nature? No, they are simply artistic license.
