How Color Blinded People See the World Wide Web

I am just surfing the colorful world wide web and thought how a color blinded person see this web.

Color blinded people cannot tell the difference between certain colors that normal people differentiate.

I am using www.kify.com as example to show you the world of a color blinded person.


1)
Normal Eye - No Color Blindness




2) Protanopia
- Complete absence of red retinal receptors





3) Deuteranopia
- Complete absence of green retinal receptors




4) Tritanopia
- Complete absence of blue retinal receptors




5) Protanomaly
- deficiency of red retinal receptors




6) Deuteranomaly
- deficiency of green retinal receptors




7) Tritanomaly
- deficiency of blue retinal receptors
