Types of Color Blindness

Red-Green Color Blindness

The most common form, caused by missing or defective red or green cones, making it hard to distinguish red, green, yellow, and brown.

Blue-Yellow Color Blindness

Rarer, involves difficulty distinguishing blue from green and yellow from violet/red.
