I can’t understand what are the true colors of various different space photos. I know that they are colorized, but how? How human eye could see space, galaxies and everything “in person”? I can’t comprehend it

If you go outside on a clear night far from the city you can see the Milky Way and Andromeda.
They’re very pale and faint, difficult to discern at all. If there’s a nearby light source you won’t be able to see the Milky Way at all, and that’s saying a lot considering you’re inside it.
So the answer is you normally wouldn’t see anything at all for these very large structures. They’re so massive and diffuse that you’re never “close” to them even when you’re literally within one of them.
Only with huge mirrors collecting light for hours can we generate a crisp image of them.
A lot of telescopes also function in wavelengths humans can’t see, and so those pictures are adjusted into visible light wavelengths for your comprehension.
