Understanding Colorblindness

For the record, color blind people can only see black and white is not true. This is because it is extremely rare to be totally color blind or has complete color vision deficiencies. There are many different types and degrees of colorblindness but they will not be posted to due to complex discussion.

Although some cases of this deficiency can be due to aging, nearly all color deficiency of significant degree is hereditary, congenital (you're born with it), and permanent.

Before having your own colorblind test here, here are some pointers on how teachers and parents can help children with this kind of deficiency:

1.0 Label a picture with words or symbols when the response requires color recognition. Label coloring utensils (crayons, colored pencils, and pens) with the name of the color.

2.0 Use white chalk, not colored chalk, on the board to maximize contrast. Avoid yellow, orange, or light tan chalk on green chalkboards.

3.0 Teach color deficient children the color of common objects like green for grass, and blue for the sky.

4.0 Try teaching children "all" the colors. Remember, most color deficient children can identify pure primary colors. It is normally just different shades or tints that give them problems.

5.0 Photocopied parts of any kind of book printed with colored ink. Black print on red or green paper is not safe. It may appear as black on black to some color deficient students.

6.0 Make sure a child's color vision has been tested before they have to learn their colors or color-enhanced instructional materials are used.

Now, here are some colorblind tests you can use for yourself and your children. If you find them small, you can copy paste them to your computer with free of charge.


Let your children enjoy the rainbow because just like life, our world is so colorful!
