In another thread Karlos provided a really useful link, here is an extract:

@Karlos

Protanomaly (one out of 100 males):
Protanomaly is referred to as "red-weakness", an apt description of this form of color deficiency. Any redness seen in a color by a normal observer is seen more weakly by the protanomalous viewer, both in terms of its "coloring power" (saturation, or depth of color) and its brightness. Red, orange, yellow, yellow-green, and green, appear somewhat shifted in hue ("hue" is just another word for "color") towards green, and all appear paler than they do to the normal observer. The redness component that a normal observer sees in a violet or lavender color is so weakened for the protanomalous observer that he may fail to detect it, and therefore sees only the blue component. Hence, to him the color that normals call "violet" may look only like another shade of blue.


Under poor viewing conditions, such as when driving in dazzling sunlight or in rainy or foggy weather, it is easily possible for protanomalous individuals to mistake a blinking red traffic light from a blinking yellow or amber one, or to fail to distinguish a green traffic light from the various "white" lights in store fronts, signs, and street lights that line our streets.

Spot on for me too, although I was diagnosed with Extreme Protanomaly. Wonder how much difference that makes, I know one thing, it thwarted my dreams of becoming a Pilot.

My particular colourblindness is quite difficult to characterise properly.

I was first diagnosed as an extreme Deutanome, but more detailed tests showed I was between that and cone monochromatic.

The specific problem, as far as they could ascertain, is that I have far to many S cones (short wavelength, ie blue) and a much reduced number of L or M cones.

My eyes are hypersensetive to some shades of blue, particularly that neon blue colour that way too many people are now fronting their take outs with :-D

It's like looking at burning magnesium *squint*

Aha. Now I understand that wierd triangle of your avatar. It's colour triangle as you perceive it. Freaky.

@Cymric

Congratulations, sir, you have solved the first challenge on the Path of Chromination ;-)

If you can deduce the remainder, you are welcome in the new world order :evilgrin:

Muhahaahaaaa... *cough*

So what are all theese purple and green lines I keep seeing?.....OOh ....it's all melting...

Yeah, now all we have to do is tinker with his cones and he'll fit right in :-P

Gee thats harsh, can't say I've ever experienced something that extreme, although driving can be a tad tricky at times. When I was initially tested, they thought that I would find it near impossible to even see the car in fronts brake lights, but that is yet to prove a problem for me.

What I find most difficult is trying to tell the difference between shades and similar colours, what looks brown to a "norm" may look red to me and vice versa, same with green, I may confuse that for brown and vice versa. It doesn't cause me any major grief but it still feels like a huge kick in the knackers when I try to do a Ishihara test and all I see is a bunch of dots. I wonder when mdma will finally give in and take the test :-P

Greetings,

After a long an eye tiring day, here's something to relax that tired eyes! :-D

If you're using opera, try magenfying it to 240%.... :-o

I take it that watching Tron in the cinema is a no-go then? :-P

You'll not be buying a Volkswagen at any point in the near future either!

That movie was an arsefez for many reasons even before we get that far ;-)

The typical VW dash isn't that bad. It's quite a narrow range I'm hypersensetive to, and that's just on the longer wavelength end. It still looks a bit harsher than I'd like, but you don't spend all day looking at it.

The biggest problems are seeing traffic lights at a distance. Until I'm close enough to observe the enclosure, its very difficult to tell which colour is on. At night, it can be difficut to even see a traffic light amidst all the normal lights etc on your typical highstreet.

But, my good man, surely a fez can't be luminous blue? Even an arsefez worn by a Smurf has to be red, innit? :-P
