Rex, I could always see, blue, yellow oranges, my color blindness is a very light red and light brown/green when they are close together. Nothing will fix that but I have a better chance of seeing those color by themselves now as they now are more vivid. .That cataract is basically a yellowish, brownish creamy color that impacts the colors and detail you see. The doc told me its like looking through a par of brownish tinted sunglasses. Even during the surgery after the laser did its work and since you are awake and told to stare at the center of this laser, I could tell when the cataract was broken up things got clear. OF course your eye is held wide open with some medieval contraption, but after the doc using some little sucker removed the pieces of the old cataract and install and did a unfold of the new lens, I could see the clock in the room and white is really white..
A little video kinda shows the procedure,
