Yellow, orange, and red … oh my!

One of my favorite aspects of fall is seeing the leaves change color from green to vibrant shades of red, orange and yellow. There’s nothing like taking in the beauty of all types of trees radiating a wide variety of autumn colors around this time of year. To me, it brings back nostalgic memories and announces that fall is here!

However, for some of us, that experience could look quite different. Color vision deficiency, commonly (yet incorrectly) referred to as “color blindness,” affects millions of people around the world. It is more prevalent among males than females because the X chromosome in a gene carries it. Color vision deficiency doesn’t allow certain color-sensing cells to develop in the retina.

VSP optometrist Ryan S. Nakamura, O.D. shared some insight on color vision deficiency and tips for parents of children with color vision deficiency:

“I test all children for color vision deficiency as it may affect their schoolwork since some learning tools in school are color-coded. The most common form is Red-Green color vision deficiency and it affects about 8% of males and 0.5% of females. If I determine that color vision deficiency is present, the most commonly asked question is, ‘How will this affect my child later in life?’

“It’s important to inform your child’s teachers about the color vision deficiency. Teachers and parents might need to modify assigned tasks. Occupational choice later in life may also be affected. Before pursuing a profession where distinguishing colors is important, young people with color vision deficiency and their parents should research the occupation.”

Check out the images below for a glimpse of what the world could look like if one is experiencing color vision deficiency. Please visit The Center or contact your VSP doctor for more information on color vision deficiency and other vision-related topics.

I’m pretty competitive. To be totally honest, VERY competitive. This manifests itself in various ways, up to and including taking online tests of all types. So, when I found the Munsell Hue Test, I thought I was up to the challenge. Just rearrange the colors according to hue. How hard can it be?

The test is based on the Munsell color system, developed by Albert Munsell at the turn of the 20th century as a way to identify colors in a scientific fashion. He based the system on three elements: hue (the actual color); value (lightness); and chroma (color “purity”). The system allowed for a standardized perception of color, and forms of it are still in use today.

Scoring on the hue test is like golf – the lower the score, the better you’ve done. I took the test and scored 21 out of 99. Thinking that was a pretty respectable score, I posted it to my Facebook page, throwing down the gauntlet for my friends.

Lo and behold, my husband scores a 4! And that’s quickly followed by a perfect score of zero from one of the graphic designers here at VSP. I suppose that’s one of the reasons why she’s so awesome at what she does. For the time being, I’ll keep my day job.munsell

It amazes me what minuscule nuances our eyes can discern (some more than others!). Learn more about how eyes detect color.

Why don’t you see how you rate? Take the test now, and share your score in the comments.
