What Is It Like to Have Some Form of Colorblindness

I've been colorblind my entire life and it's not really a severe problem, it just means some things will be more annoying to you than to other people.  Coloring assignments in elementary school were annoying, as were really anything that required coloring.  I read the labels on crayons and markers.

Color-coded systems are also frustrating, which is why color should always supplement some other system whenever possible.  It's not always possible and sometimes color just makes sense.  Airports are marked with rotating green lights.  Ships mark their port and starboard sides using colored lights.  And of course, the question I get most often, we have red and green traffic lights.  So how can I see those?  I don't know, I didn't make my eyes, but I do know that I can pass the vision test at the RMV and that I've never caused a wreck and I've been driving for 19 years.

It is extremely difficult for me to drive at night because stale green traffic lights look exactly like sodium vapor street lamps and oncoming vehicle headlamps.  Local roads at night are most frustrating.  If I have to drive at night, I prefer controlled access roads.  But then again, I just avoid driving long distances at night.

I dislike those high intensity discharge headlamps that BMW and other manufacturers started using.  I also dislike it when people remove tail light lenses and replace them with clear lenses.  You start making everything look the same.  At least give me a fighting chance!

This is a really common image that shows up to describe to people what it's like to have forms of colorblindness.  It's ok, but not great.  People need a better example with a wider range of colors.  And I found site that does a good demonstration.

Colour Blindness Simulator

Upload a JPEG image not larger than 100k and 1000x1000 or lower in resolution and it can convert it to provide a reasonable demonstration for protanopia, dueteranopia, or tritanopia.  I tested it using a recent picture of our daughter.

How I See It

And there it is.  I asked Karen to look at it and see if it looked different.  She said it did, so hopefully I saved the right images here because they look the same to me.

I have slightly weak color sensitivity. Not enough to call me any kind of "color blind" but on more thorough tests I underperform in areas.

Usually it doesn't affect life at all, but on my new laptop, IRSSI's red "look at me" numbers, drawn on a blue background, are very hard to distinguish. I haven't had this problem on any other monitor, the specific color output of this one just happens to hit my weak spot just right. It was eye opening to suddenly be affected in this way, even if normally my color vision isn't even bad enough to be noticeable.

On the plus side, your daughter might be a tetrachromat, so she has a small chance of having super vision :)
