A friend found out today that her youngest son is colorblind, like both of his older brothers. It got me thinking.
What kinds of things are there that being colorblind would make more difficult? Are there things that you simply can't do?
The most typical thing people think of is a traffic stoplight, but the first thing to come to my mind was reading the color codes on resistors, something I needed to do at one of my earliest jobs. Can't do that if you can't distinguish between some colors. I hunted up some info and found out that many resistors these days have numbers printed on them as well, eliminating that potential problem.
As I was looking for information, I found a couple of cool things.
One is a test to find out if you are colorblind. No, not the typical one where you look at the circles of colored dots and tell them what number you see. It's one where you match colors. Try it. It's interesting. It's called an anomaloscope.
Then, I found a site with all sorts of information about colorblindness in the medical field, including some images that show skin conditions that can be difficult for a colorblind person to see. I hadn't even considered that! Things like pallor, flushed skin, or cyanosis can be much more difficult to detect.
I don't know that I know anyone in EMS who is colorblind, but statistically, I probably do. Do you? Have you ever heard of anyone having a problem with it?
