SELF-CHECK
Check how easily you tell colors apart.
Measure how well you distinguish red-green and blue-yellow with a self-check, then automatically tune the correction strength to your results. Supports type 1, type 2, and type 3, and lets you create profiles.
COLOR VISION
Color vision comes in types.
Inherited differences in color vision affect about 1 in 20 men and 1 in 500 women in Japan. The type depends on which of the three kinds of color-sensing cells (cones) in the eye works differently.
- Type 1 (protan)
- The cells that sense red light work differently. Red and green, or red and black, can be hard to tell apart.
- Type 2 (deutan)
- The cells that sense green light work differently. Red and green, or orange and yellow-green, can be hard to tell apart.
- Type 3 (tritan)
- The cells that sense blue light work differently. Blue and green, or yellow and purple, can be hard to tell apart. This type is very rare.
SeeHue supports all three types and lets you tune the correction to how strongly each one affects you.
