Color blindness not a form of blindness, but inability to view in the way you see color. With this vision problem, you have difficulty distinguishing certain colors, such as blue and yellow or red and green. Color blind people can see colors but the way of perception may differ. Color blindness occurs when retinal light-sensitive cells are not able to respond appropriately to different wavelengths of light. The most common inherited form of color blindness (red-green) is caused by a common X-linked recessive gene.
