In one of last years quizzes, I asked the following question.
So I decided to test this out as best I could. I pointed my telescope at a very rich star field in the Milky Way arm between Eta Carina and Crux. It is a stacked image but I have done my best not to skew the image colour balance. I did boost the saturation
When examining the image, bear in mind that red dwarfs have low absolute magnitudes. Consequently, they are faint unless they are close to us. Blue stars are highly luminous and therefore visible from much greater distances.
I'm convinced but you be the judge!

Joe, great image. Like Jean-Yves, I'm still counting.
What struck me was the variety of colors. Also, I can't tell if your image should be grouped with Rorschach test images or color-blindness images! Just kidding!
In part, my motivation was to question my habit of rendering the general Milky Way glow as a warm toned yellow-orange colour.
Is it the correct approach or should it be blue as I see on social media? I have often seen Milky Way images with the core area rendered blue or blue white.
Following this little fun experiment plus some reading on spectral type abundances, I am more convinced than ever that I should continue rendering the Milky Way with a warm colour temperature not cold blue.
