2. Can you see the green word?

Some people may sense green correctly while suffering with other hues. Because green is so common in nature and in signals and signage, color-blind people frequently devise techniques to navigate its different shades, relying on context clues or alternative visual information to decipher its significance.

3. Can you see the purple word?

Depending on the specific impairment, people with red-green color blindness may perceive purple as closer to blue or red. Similarly, people with blue-yellow color blindness may have difficulties seeing the red component of purple, making it appear more blue. Despite these problems, the distinctiveness of purple in many circumstances, combined with surrounding clues, can help color-blind people identify it, but with potential differences in perception compared to those with normal color vision.
