What are the signs and symptoms of color blindness?

You might have a form of color blindness if you have trouble:

• Telling the difference between certain colors.
• Seeing the brightness of certain colors.
• Distinguishing the difference between certain shades.

The signs and symptoms of color blindness can vary depending on the type. If you have inherited your color blindness (hereditary color blindness), the signs are often barely noticeable because you’ve always seen colors the same way. You may not realize that there’s a different way to see colors. However, if you have acquired color blindness — meaning you have color blindness because of an injury or illness — you may notice the shift in how you see colors, although some diseases affecting color vision progress too slowly for changes to be noticeable.
