Generally, the color vision defect will cause loss of color saturation ... in plain English that means colors will not be as bright, specifically in the red spectrum. Try this if you are having ON: Cover the affected eye and look at a red pen cap. Consider that color worth 10/10. Now cover the good eye and look at the pen with the affected eye. What is the color worth, compared to the other eye? 2/10? 5/10? That is called the red cap desaturation test. If your color vision is affected due to ON you will clearly see the difference.
