Your eyes each send a color signal to the brain and the brain processes the color based on both signals it receives just as both eyes are necessary for depth perception. You would not use one eye when you use your binoculars would you? Many peoples eyes also vary in how good they process color. In fact in this thread a few people have said they are less proficient at detecting colors in one eye. Using your eyes as a test for whiteness is introducing another error into the formula. As Chosun says:"All I have to do now is figure out how all of that relates to my two different colour cast seeing eyes (one golden orangish, the other bluey-greenish), my transition lens eyeglasses and Mr Magoo-like myopia!"  And here is a thread on how people see different colors with each eye:<a href="https://www.physicsforums.com/threads/color-difference-between-left-and-right-eyes.493556/" target="_blank">https://www.physicsforums.com/threads/color-difference-between-left-and-right-eyes.493556/</a></blockquote>
