What Does It Look Like?

Ever wondered what the world looks like to people with color blindness? Curious minds often wish to see through the eyes of others. Check out the photos on the right to better understand and empathize with fellow travelers in life.

As designers, we have special interest in color blindness – more correctly called “Color Vision Deficiency” and more properly called Dyschromatopsia – as we work daily with colors.

We can better provide for those with color vision deficiencies by taking it into consideration as we design our websites, ads, illustrations, logos, typography or any visual communications.

Photos Show Vision Types

Photos, to the right, show types of color blindness accessable on the ColorJack “Vision” menu:

The less severe type, Anomalous Trichromacy, includes:

The moderately severe type, Dichromacy, includes:

  • Protanopia – reds are greatly reduced (1% men)
  • Deuteranopia – greens are greatly reduced (1% men)
  • Tritanopia – blues are greatly reduced (0.003% population)

The most severe type, Monochromacy, is very rare: all (Achromatopsia aka Rod Monochromacy), or most (Achromatomaly), color vision is lacking.

The “Customaly” option offers the opportunity to create your own custom vision deficiency!  :o)

Causes of Color Blindness

Color blindness is usually passed on at birth, but can come about through illnesses or accidents. Causes are generally related to the eye’s retinal cones being defective or absent. Delve deeper into color blindness by researching via Wikipedia, U of I Eye Center, and Health A to Z.
