A costume rendering by the author adjusted with Vischeck, an application that simulates what a person with
protanope, deuteranope, or tritanope color deficiencies might see.

greenish colors; and S cones to short wavelengths, bluish colors. In people with color deficiencies, a type of cone is either missing or has a
different sensitivity. Acquired color deficiencies
can be caused by injury, disease, or even certain
medications. The causes of color deficiencies
are not of great importance for teaching these
students. Rather, the type of color blindness and
the degree to which students do or do not see
certain colors are vital in determining how to
assist them in design disciplines.
The first type of red-green color deficiency is known as protanomaly and affects
the L-cones, creating a red weakness. A person with protanomaly tends to see red, orange,
yellow, and yellow-green shifted toward green
in hue, but all these colors also appear paler
than normal. Violet, lavender, and purple appear to be shades of blue because the reddish
components are diminished. The other type
of red-green color deficiency, known as deuteranomaly, affects the M-cone and indicates
a green weakness. Although this type is similar to the other, the colors do not tend to be
dimmed. The names red, orange, yellow, and
green don't mean much to the person with
deuteranomaly, as they all appear to be the
same. Violet, lavender, purple, and blue also
appear to be similar in color.
The blue and yellow color deficiency is
called tritanomaly and affects the S-cone, creating a blue-yellow weakness. These individuals
have difficulty distinguishing green, cyan, and
blue. They may also have trouble distinguishing
yellow from violet. There is also often confusion
with pink, orange, and brown.

What do color-deficient eyes see?
Although you may encounter more than one student in your class who is red/green color deficient, you will soon discover that they see color
differently from one another as well as the rest
of the class. It is important to be mindful of this,
as each student will need a different level of assistance on a given project.
Samples of the three types of color-deficiency can be seen here using a recent sketch
from Hairspray produced at Western Michigan
University. These images were run through the
Vischeck system available as a free download for
your computer or for use at the website. Load
any image into the system, and it replicates what

the color-blind student may see when looking at
the image or page. Check it out at http://www.
vischeck.com/vischeck/vischeckImage.php
This handy system allows you to get a
sense of what your student is seeing. It is useless to ask color-deficient students if the Vischeck image represents what they see, as their
eyes will continue to shift the colors in any image shown.
As you can see from these examples,
the colors can shift drastically away from the
original. This system is very useful to get an
understanding of various color deficiencies,
but note that it is only a representation of the
color deficiency type; it's important to remember that the students you are working with will

General teaching notes that will help the student in a standard classroom
* Use white chalk on a green or black chalkboard. Avoid colored chalk for
emphasis.
* Use a black marker on the white board. If using a red marker, don't use green
for emphasis, as these colors appear similar. Avoid contrasting colors, as these
actually often look similar to the color-blind student.
* Avoid the technique of color-coding items for the classroom. Colored pie charts
and color-coded maps are usable for the color-blind student but need labeling
using a color key. If possible avoid it all together, or use only a few colors.
* Avoid color-coding in testing as this puts the student at a disadvantage.
* Handouts should be Xeroxed and printed in black and white to aid the student.
The use of colored ink can be problematic as the student may not be able to see
all of the text on the paper.
* Avoid using colored paper for printing.
* Select backgrounds for Power Point presentations that give a good contrast between
the background and the text. Avoid using multiple colors for the text as this can cause
problems for the student.
