A bit about my colorblindness...

My Colorblindness

I am color blind to a degree. I am not sure of the exact nature of my deficiency (it has been a long time since I was tested), but from tests I have taken online it appears that I have Anomalous Trichromasy (anomalous vision, all three color cones presnet) most likely Protanomaly (anomalous green cones). While I do have red/green cones, some are either missing or are not functioning properly. The image below was generated with the help of the Colorfilter link below.

Protanomaly (anomalous red cones)
Media_httpydantcomzen_zjdla
Deutanomaly (anomalous green cones)
Media_httpydantcomzen_rggip
Tritanomaly (anomalous blue cones)

The images for the normal logo and the protan logo are almost 100% identical to me. The deutan image is close to the normal logo, however the Gs are darker in the deutan link (slightly more purple). The tritan image looks nothing like the normal image - it is washed out (except the o and e) and entirely in shades of red.

Actually those images represent dichromatism not anomolous trichromatism. They are, protanopia, deuteranopia and tritanopia. Indeed weakness to a colour is more common than blindness, most common is Deuteranomally. Deuteranomaly is actually not a colour defficiency. If you think about what causes it, they would have something that most of us don't have and it has been found they can better distinguish certain shades of khaki.
