If I close one eye for a few minutes and then switch which eye is closed I see a very (very) subtle difference in hue.
Left eye sees a green tint; right eye sees a pink tint. It’s more obvious when I’m looking at a white wall on a bright day.
I don’t get this effect if I don’t let one of my eyes adapt to the dark first.
Did you ever wear those old-school 3D glasses?
This is ironically how I discovered I had this. I took off the glasses and took turns looking with one eye closed to see the effect. I randomly did it some time later without the glasses on out of curiosity and noticed there was a slight color shift. Young me thought it was the 3D colored glasses that damaged my eyes.
