Types of Color Vision Deficiency
About 1 in 12 men and 1 in 200 women have some form of color vision deficiency. Understanding how your content appears to these users is essential for creating accessible designs.
Learn about different types of color vision deficiency
Color Vision Deficiency Categories
- Dichromacy: Complete absence of one type of cone cell
- Anomalous Trichromacy: Abnormal function in one type of cone cell
- Monochromacy: Absence of two or all cone cell types
Dichromacy (Missing one cone type)
Protanopia
Absence of red cone cells (L-cones). People with protanopia see reds as darker, and have difficulty distinguishing between reds, oranges, yellows, browns, and greens.
Affects ~1% of males and 0.02% of females
Deuteranopia
Absence of green cone cells (M-cones). People with deuteranopia have difficulty distinguishing between reds, yellows, greens, and browns, similar to protanopia but with subtle differences.
Affects ~1.2% of males and 0.01% of females
Tritanopia
Absence of blue cone cells (S-cones). People with tritanopia confuse blues with greens, and yellows with violets, making blue-yellow discrimination difficult.
Very rare, affects fewer than 0.001% of people
Anomalous Trichromacy (Weakened color perception)
Protanomaly
Abnormal red cone cells. Reduced sensitivity to red light, with red colors appearing dimmer and less vibrant. Milder than protanopia.
Affects ~1.3% of males and 0.02% of females
Deuteranomaly
Abnormal green cone cells. The most common type of color blindness, causing a reduced ability to distinguish between reds, greens, browns, and oranges.
Affects ~5-6% of males and 0.4% of females
Tritanomaly
Abnormal blue cone cells. Reduced sensitivity to blue light, causing difficulty distinguishing blue from green and yellow from violet. Milder than tritanopia.
Very rare, affects fewer than 0.01% of people
Monochromacy (Severe color vision impairment)
Achromatopsia
Complete color blindness where all cone cells are non-functional. People with achromatopsia see the world in shades of gray, have poor visual acuity, and are extremely sensitive to light.
Extremely rare, affecting approximately 1 in 30,000 people
Achromatomaly
Partial color blindness where cone cells are partially functional. A milder form of achromatopsia that causes colors to appear washed out and reduced contrast sensitivity.
Very rare genetic condition
Did you know?
Color blindness is much more common in males than females because the genes responsible for the most common forms are on the X chromosome. Males have only one X chromosome, so one altered gene is enough to cause color blindness. Females have two X chromosomes, so both must be altered to cause color blindness.
