LRGB M31 Andromeda Galaxy (the Andromeda Galaxy)

You're kidding) Maybe I'll also shoot about 10 hours of L and it will stand out even more.

)))

It absolutely can be. There's spectrophotometric color calibration, white balance correction, and just boosted saturation across the whole galaxy. Nothing was processed or colored separately. The colors weren't changed. All relationships between brightness and color are preserved. The colors are natural and match expectations. Yes, you could reduce saturation by half — it would look more natural, but less vivid. I, in turn, could have pushed saturation even higher to farm likes, but I stopped at 2/3 of the way (vivid but not toxic). Maybe your monitor also displays color somewhat differently. If you solve the purple problem in your work, you'll also be able to raise saturation and see the orange color)

And so, to not be unfounded, here is a NASA reference for you: https://science.nasa.gov/mission/hubble/science/explore-the-night-sky/hubble-messier-catalog/messier-31/

Well okay,
you convinced me((
But purely in my humble opinion, I would just try to clean up the red in curves.

I was actually struggling with the red because it was coming out magenta) I actually liked it, but people said it wasn't the reference standard and I had to fix the WB =)
