Color vision is a function of the optic nerve. Some people are born color-deficient and they perceive colors differently than normal. However, that is usually bilateral. It concerns me somewhat that you view colors differently in one eye. If you are under age 50, this should be evaluated, preferably by a neuro-ophthalmologist. He or she will test your color vision, look at your optic nerves, and maybe even perform other tests of visual function such as a visual field. If you are "cataract age" then asymmetrical cataracts may be a simple explanation. But it seems you went to an ophthalmologist, so you would have known if you have any early cataract. We often evaluate optic nerve function using the "red desaturation test". Look at something bright red - it should appear similar bilaterally. If not, I would evaluate this further.
