Decent description of an everyday affliction. There was me all ready to save up and invest in some shades

Color Blindness Test Result

Extreme Deutan

Extreme deutans (“doo-tans”) have a severe or complete red-green color blindness.
Extreme deutans generally do not get the “wow-effect” from the EnChroma lens. Color vision may be improved, but the effect is subtle and takes a significant amount of time to adapt to (anywhere from days to weeks). In some cases, there may be no noticeable effect at all–these types are calleddichromats, where the individual effectively has no M-cone photopigments).
Based on feedback from people with similar results, we believe there is about a 50% chance that EnChroma glasses will help your color vision.
All EnChroma products are satisfaction-guaranteed within 30 days of purchase.

Symptoms for Extreme Deutans

Significant Color-Name Confusion
Green, brown, yellow, orange, and red may appear confusingly similar. This makes “naming” the color difficult. Blue and purple are very frequently confused. Pink can be very “muted” so it looks essentially gray.
Difficulty with Traffic Signals
Green lights may appear to be white. Yellow and red lights may appear indistinguishable, especially at night. People with color blindness may react up to 30% slower to color coded information, which affects their ability to safely operate a motor vehicle.
Impaired Color Perception
The perception blue and yellow shades is good, but red and green colors seem muted and dull. A person with extreme deuteranomaly can typically perceive about 25 thousand distinct shades of colors, which is just 2.5% of the 1 million shades seen with normal color vision. A person with deuteranopia has total loss of red-green color perception and can only see 10 thousand distinct shades (1% of normal).
Distorted Color Perception
For people with normal color vision, there is universal agreement on what certain “unique colors” look like. However due to the significant spectral shift of the M-cone, strong deutans may perceive these colors to have different spectral locations, for example, something as ordinary as peanut butter, which should look brown, appears to be green for someone with color blindness!

Is that similar to the Wu-Tang clan?

For our works annual eye test for seeability and colour blindness we also had to do a shades of grey test for the first time this year.

There was a certain amount of trepidation before going in the little room.
