COLOR BLINDNESS – LEARN ALL ABOUT IT

"Colblindor at www.color-blindness.com presents all you ever wanted to know,
learn and try out concerning color blindness. Please feel free to browse the
site and find online color blindness tests, some tools to check color names or
many interesting facts. I hope you will find a lot of useful information on any
form and type of color vision deficiency. If you still have an open question,
feel free to contact me directly." — Daniel from Colblindor


Color blindness (or colour blindness — or more specific color vision deficiency
(CVD)) is well known but hard to imagine if you are not suffering from it. So
usually people are either looking for more information to learn about color
blindness and all its details, would like to better understand the vision by
simulating it or want to test themselves with some form of color blindness test.
All this you can be found here on color-blindness.com — and much more.

Latest news on Colblindor about Color Blindness:



NEW RELEASE OF COLOR BLINDNESS SIMULATOR



Color blindness affects approximately every 1 in 12 men (8%) and 1 in 200 women
(0.5%). This means there is definitely one in your neighborhood or school class
affected by it. Most of them are male, because the most common form called
red-green color blindness (a term wich is also misleading) is encoded on the
x-chromosome and therefore sex-linked. As red-green color blindness is inherited
from a mother to her son, a father never passes this type of color blindness on
to his male children.

FREE COLOR BLINDNESS TEST APP: COLOR BLIND CHECK



The term red-green color blindness is often used but actually not quite correct.
Ever type of color vision deficiency affects the whole color spectrum and
therefore can not be reduced to just certain colors. Of course, for the most
often encountered types Protanomly (the milder form or red-weakness) or
Protanopia (missing red cones, red-blindness) and Deuteranomaly (green-weakness)
or Deuteranopia (green-blindness) the colors red and green are the most
problematic and misinterpreted or indistinguishable ones. But people suffering
from any of those forms have issues with the red or green part in every color,
so the whole spectrum of colors is affected.

Besides red-green color blindness, which is encoded on the x-chromosome
(sex-linked) and therefore much more common for men, there are also forms of
color vision deficiency which are evenly distributed between male and female
like Tritanomaly (blue-weakness) or Tritanopia (blue-blindness) and the real
color blindness Achromatopsia (monochromacy) or the so called blue-cone
monochromacy (only blue cones).

Color blindness simulation is fascinating! If you are not colorblind it is so
hard to imagine what it looks like to be colorblind: Which color do you see? Do
you see any at all? What does it mean not to be able to see red? and so on. My
COlor BLIndness Simulator is a handy tool which allows you to use your own
images and try out all the different simulation types. It is even possible to
save any simulated image and have a one-by-one comparison.

Online color blindness testing is often done but unfortunately no yet as good as
it could be. Usually you’ll find out about color blindness at school or when
visiting an eye specialist and want to confirm this with some online tools.
There are online color blindness tests available, but most of them are not
reliable and cannot compensate a visit at your eye specialist. There is a new
form of color blindness test coming up: Color Blind Check uses a new method and
its results look very promising. But this new form still needs more time to
develop and calibration to count as a trustable color blindness test.

COLOR VISION DEFICIENCY STARTING POINTS

A good place to start with is my free eBook: Color Blind Essentials, which you
can either read on- or offline. Otherwise you could begin wich some of the
latest articles, try some color blindness tests or get started with answering
the question What is color blindness? About 8% of all men and 0.5% of all women
are suffering from some form of color vision deficiency (CVD) – yes, women can
also be colorblind but as the most common form is encoded in the x-chromosome
(sex-linked), there are much more men affected by it.


LIST OF 50 FACTS ABOUT COLOR BLINDNESS

Check out a list of 50 facts on Color Vision Deficiency. From achromatopsia to
population statistics, from red-green color blindness to different types of
tests. This list of 50 CVD facts offers a nice overview in a compact form.


COLOR BLINDNESS SIMULATION TOOL

Ever wanted to see how it looks like if you are colorblind? Try out Coblis -
Color Blindness Simulator. Through this online tool you can transform any image
and see how it looks like with different forms of color vision deficiency.


RED-GREEN COLOR VISION DEFICIENCY

Red-green color blindness is by far the most common type of color vision
deficiency. Unfortunately this term is a little bit misleading and doesn't
respect all the facts. There are different types of color blindness which can be
distinguished into protan (red-blind), deutan (green-blind) and tritan
(blue-blind) color vision deficiencies – not to forget real color blindness
called monochromatism. Every type has different severities (Protanomlay/
Deuteranomaly/ Tritanomaly) up to a complete missing of certain cones
(Protanopia/ Deuteranopia/ Tritanopia).


ISHIHARA 38 PLATES COLOR BLINDNESS TEST

Since the last century the Ishihara Color Blindness Test is the most well known
and the most used color vision test worldwide. Different series of plates are
available (view the 38 plates edition) and used to identify different types and
severities of cvd. But there are also other color vision deficiency tests
available and some of them implemented as online color blindness tests. The
future in cvd testing is either a genetic testing approach or using touch
devices, which is well demonstrated by the Color Blind Check android app.
