Colour Blindness...
« on: June 15, 2005, 02:18:05 AM »
In another thread Karlos provided a really useful link, here is an extract:

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.

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*


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

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*


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

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.


I know from a distance I can't tell the difference between Red and Orange and at night green blends in with headlights and street lights.

I wonder how those same images will look in adz-o-vision?


That had me rolling for a second there :roflmao:

Seriously, I really don't know how to describe how they look because the way I see the world, it appears normal, yet to a "norm" it would probably be quite odd indeed. Best example I could use would be the grass, a norm would be able to see distinct variations in hue with the different types of grass/weeds present, whilst it would all appear the same tone of green to me. I honestly don't think I see a different colour scale, but I know I don't see as many colours.
