Why does philosophy constantly twist things into an over complicated mythical mess, and then act like it’s some novel insight? Like the things with colors: they only exist subjectively so they aren’t real in any other sense than being observed, so it’s only the observation that makes them real, and does that mean they are even real???

Yes, they are. Subatomic particles vibrate (or absorb vibrations) at specific frequencies, and therefor emit electromagnetic waves at certain frequencies when stimulated. That is real and objective. Evolution has left us with sensors and neurons that can detect and interpret some of these frequencies that appear to us as colors. That is subjective, but the science behind it is not. That’s what happens. Is the color real? Well, define the question better and there is an actual answer. The vibrations are real. Your interpretation is also real, but in a different way. Does the color exist without an observer? Well, what’s your definition of color? Does a tree falling in the woods with nothing to hear it make a sound? Well, what’s your definition of a sound?
