It's still not really clear what you are seeing. It would help if you could post an example of your shot, and what you would like to get it to look like. As you have already noticed, color can be very subjective (certainly in perception), but even that statement can cause arguments here since there is a case to be made for a "scientifically correct" color. Most of us are just tying to make things that look aesthetically pleasing (IMO), and that gets personal. Some here are more science-oriented. It can get contentious.
If you are seeing a color "cast" (e.g. it all looks red or green or something), then that may be a processing error. Please post an example.
Meanwhile, maybe I can illustrate what posters like #3 and #10 have already shared. Galaxies are not generally colorful! You need long integration times to capture their colors -- and practice. Personally, my early steps with DSLRs (regular cameras) did not show any color in galaxies at all. Later, with a dedicated astro color camera (OSC), I started to see some colors, with more practiced processing. Only when I then moved to a mono astro camera with filters, and even more practice at processing, did I start to get the colors I really wanted.
Here is my progression for M33 -- top to bottom:
- 2014 - DSLR (astro-modified, even) -- no color
- 2019 - OSC astro camera -- some color, better but still early processing skills
- 2020 - Mono astro camera -- much better, though still room for improvement in 2021 and maybe add some Ha filter to experiment!
