I realize right before creating this thread, I saw the screen subtly bluer in my left and subtly redder in my right. I thought my eyes were developing a serious condition, but it surprised me after a quick Google search. It's normal having different hues between the two eyes. Some cold, warm, colder, or warmer. Maybe I'm just tired? I'm now very curious on whether you're eyes see the same hues or not?
Years ago I looked out a window and saw some grass, noticed it a large patch looked yellow and dead but only one eye could see it. A bit later happened to glance out with both eyes able to see and noticed it looked almost fully green. Testing both eyes individually and then together again pointed out a similar problem for me. If you are really curious, try some of the online color blind tests one eye at a time then together.
i dont have a colour difference between my eyes but a difference in light perception. separately, one eye sees things brighter than the other eye but is slightly less focused in exchange. had optometrists examine my eyes and found nothing wrong with them that would affect my vision. human eyes seem to have some variance in capabilities when they're looked "through" separately as opposed to the normal way of looking through both as a combined image.
My guess is that you have some form of color blindness in one of the eyes? I don't really know much about the subject, so it's a bit of a wild guess. I never experienced this myself.
