.russian colour blind test

haha, here’s the russian test which apparently i can’t see the circle 5 no matter how hard i’ve tried.

Can’t see circle 1: High agression, proneness to conflict, the recommendation is to add more physical excercise and cold showers.

Can’t see circle 2: Possible low than average intellectual abilities, can’t serve with sophisticated equipment.

Can’t see circle 3: Possible debauchery, soldier should get increased daily ration, should get more physical activity tasks, should not be connected to food supplies, etc.

Can’t see circle 4: Possible inclination to violence, can be assigend as a leader to his unit, as he can preserve discipline.

Can’t see circle 5: Possible latent homosexuality. Can be light uncontrolled accesses of attraction to the same sex.

Can’t see circle 6: Possible schizophreanic tendency. Required additional inspection.

Every soldier should be tested before assignment, according to the order #2299.”

50 Facts About Colour Blindness

#01 99% of all colorblind people are not really color blind but color deficient; the term color blindness is misleading.

#02 Red-green color blindness is a combination of red-blindness (protan defects) and green-blindness (deutan defects).

#03 Color blindness is more prevalent among males than females, because the most common form of color vision deficiency is encoded on the X sex chromosome.

#04 “What color is this?” is the most annoying question you can ask your colorblind friend.

#05 There are three main types of color vision deficiency: protan, deutan, and tritan defects.

#06 Strongly colorblind people might only be able to tell about 20 hues apart from each other, with normal color vision this number raises to more than 100 different hues.

#07 Colored lenses or glasses can improve color discrimination in your problem areas but can not give you back normal color vision.

#08 Ishihara plates are the best known color blindness tests, but they are not the most accurate ones.

#09 About 8% of all men are suffering from color blindness.

#10 Severity of color blindness is usually divided into the following four categories: slightly, moderate, strong, and absolute.

#11 The terms protan, deutan, and tritan are Greek and translate to first, second, and third.

#12 A father can’t pass his red-green color blindness on to his sons.

#13 Dogs are not colorblind.

#14 Color vision deficiency would be a much better term; but it is not as easy to pronounce compared to color blindness.

#15 There are people which are really suffering from complete color blindness, which is called achromatopsia or monochromacy.

#16 Blue-yellow color blindness would be better called blue-green color blindness, as this are more the problem colors.

#17 There exists every nuance of color vision deficiency severity, starting from almost normal color vision up to complete color blindness.

#18 Protanopia, deuteranopia, and tritanopia are types of dichromacy, which means you have only two different color receptors (cones) compared to three with normal color vision.

#19 If a woman is red-green colorblind, all her sons will also be colorblind.

#20 Colorblind people feel handicapped in everyday life, and almost nobody recognizes this.

#21 99% of all colorblind people are suffering from red-green color blindness.

#22 When using color correcting lenses you are wearing two differently colored lenses in your eyes.

#23 Red-green color blindness is a recessive sex linked trait, which causes more men to be colorblind than women.

#24 John Dalton wrote the first known scientific paper regarding color blindness.

#25 Protanomaly, deuteranomaly, and tritanomaly are types of anomalous trichromacy, which means you have three different color receptors (cones) like people with normal color vision but one of them is shifted in its peak.

#26 In certain countries you need normal color vision to get a drivers license.

#27 Deuteranomaly—one form of red-green color blindness—is by far the most common form of color blindness.

#28 More women than men are carriers of color blindness, even though they are not colorblind themselves.

#29 Some people get rejected from a job assignment because of their color vision deficiency.

#30 About 0.5% of all women are suffering from color blindness.

#31 Blue-yellow color blindness is a dominant not sex linked trait, which means both men and women are equally affected.

#32 Red-green color blindness doesn’t mean that you are only mixing up red and green colors, but the whole color spectrum can cause you problems.

#33 The anomaloscope is the most accurate color blindness test known today.

#34 Police officer, firefighter, and airline pilot are the most famous jobs which require normal color vision.

#35 There is no treatment or cure for color blindness.

#36 Pseudoisochromatic plates were introduced by Professor J. Stilling of Strassburg in 1883; the Ishihara plates by Dr. Shinobu Ishihara followed almost half a century later.

#37 Different chromosomes are involved as sources for the different types of color vision deficiency.

#38 Women can also suffer from color vision deficiency.

#39 Monochromacy—also called achromatopsia—means you have only one type of color receptors (cones) in your eyes.

#40 Color blindness is also called Daltonism, after the scientist John Dalton.

#41 The most often used types of color blindness tests are: pseudoisochromatic plates, arrangement test, and the anomaloscope.

#42 Better color vision deficiency terms would be: red-blindness for protanopia, red-weakness for protanomaly, green-blindness for deuteranopia, green-weakness for deuteranomaly, blue-blindness for tritanopia, and blue-weakness for tritanomaly.

#43 John Dalton believed his whole life that the cause of his color blindness is a colored fluid inside his eye balls.

#44 Many colorblind people have problems with matching clothes and buying ripe bananas.

#45 Quite a lot of people with normal color vision can’t pass an Ishihara plates test free of errors.

#46 The International Colour Vision Society is scientifically investigating every aspect of color vision and color vision deficiency.

#47 Confusion lines of the CIE 1931 color space show exactly the colors of confusion for all forms of color blindness.

#48 Only a whole battery of color blindness tests can reveal the true type and severity of your color vision deficiency.

#49 John Dalton was also colorblind himself.

#50 A Colblindor is a colorblind person who learned to enjoy his colorblind life

.ineffective blogger

alright, i must admit that i’m not really into blogging, thus making me an ineffective blogger. i’ll try my best to blog if possible.

anyway, i’ve researched on colours before colour blindness.

this book is really cool cos it talks about how colour can transform your life!

.a book – diagnosis of defective colour vision

ok, I went to the library some time ago and there were very few books on colour blindness. I wanted to borrow this book but unfortunately, it’s a reference book. urgh. it’s quite technical so i’m taking some time to go through the details.

 anyway, i’ve managed to zap some of the pages.

if they all looked the same to you it means you’re suffering from colourblindness:

a kid tried to colour the flag but never gets it right:

 

 Difference in perception between a normal and a colourblind:

some common colour blindness test that we’ve probably tried it when we were young:

 

ok, the tests that were used in the past were: The Holmgren Wool test and Farnsworth-Munsell hue test, never knew that!

These clinical tests were actually designed. Some may view colour blindness as a disability but I beg to differ cos I think it’s rather interesting to see how the world looks in their world, how dull things can be colourful and how they imagine what colours look like.

.corrective lenses

well, with advance technology, there are corrective lenses:

http://www.colourvision.info/colour_vision_deficiency_correction_for_color_deficient_and_color_blind.htm

but is it really necessary?

.a cool tool

take a look at this cool tool I came across:

http://www.idea.org/vision-demo.html

A simulator that demonstrates how people with various levels of colour blindness perceive colour. Try it!

.designers do take note

As according to wikipedia:

Color codes present particular problems for color blind people as they are often difficult or impossible for color blind people to perceive.

Good graphic design avoids using color coding or color contrasts alone to express information, as this not only helps color blind people, but also aids understanding by normally sighted people. The use of Cascading Style Sheets on the world wide web allows pages to be given an alternative color scheme for color-blind readers. This color scheme generator helps a graphic designer see color schemes as seen by eight types of color blindness. For an example of a map that could present a significant problem to a color blind reader, see this graphic from a recent New York Times article. The typical red-green color blind reader will find the green sections of the map nearly indistinguishable from the orange, rendering the graphic unreadable.

Designers should take into account that color-blindness is highly sensitive to differences in material. For example, a red-green colorblind person who is incapable of distinguishing colors on a map printed on paper may have no such difficulty when viewing the map on a computer screen or television. In addition, some color blind people find it easier to distinguish problem colors on artificial materials, such as plastic or in acrylic paints, than on natural materials, such as paper or wood. Thirdly, for some color blind people, color can only be distinguished if there is a sufficient “mass” of color: thin lines might appear black while a thicker line of the same color can be perceived as having color.

When the need to process visual information as rapidly as possible arises, for example in a train or aircraft crash, the visual system may operate only in shades of grey, with the extra information load in adding color being dropped. This is an important possibility to consider when designing, for example, emergency brake handles or emergency phones.

It seems to me things that are colour coded can be quite difficult for them to tell the difference. That makes me wonder.. isn’t our train lines colour coded? I think this can spur me on to consolidate things that are colourblind-friendly and non-colourblind friendly. I suppose labels with words and shapes and contrast helps in the colourblind world.

.a design perspective

I found an interesting article that basically sums up colour blindness.

http://www.creativepro.com/article/designing-color-blind

Some interesting points to note:

Some would say we all see art in our own unique way… that would be especially true for the color blind.

I guess that’s what makes everyone unique. Looking through the eyes of the colour blind is a bit difficult to imagine.

Many of the genes involved in color vision are on the X chromosome, making color blindness more common in males than in females.

So guys, beware!

And I realised that there are basically three types of inherited or congenital color vision deficiencies: monochromacy, dichromacy, and anomalous trichromacy.

.colour blindness

from wikipedia:

Color blindness, or Colour blindness, a color vision deficiency, is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals.

Although colour blindness is largely related to genetic history, it can also happen to normal people as well. Well, I’m just glad that I’m blessed that I’m not colour blind, at least for now.
