Any color-blind in the audience?

I’ve touched on this before (related to Advertising) and since I’m color-blind myself I hold a strong interest in the topic. Most important fact to repeat out of that earlier post: 8% of all Caucasian males suffer a color vision deficiency. And that might be more than you would expect.

With this in mind I said that it’s not that silly to have your ads tested to see if someone who’s color-blind can see/read everything alright. Same counts for websites obviously, but the most time I personally have problems with it is with presentations.

We all know that every single minute there’s probably someone in the world working on the most horrendous powerpoint/keynote presentation but apart from ugly presentations, some people use texts on backgrounds in a way that I can’t read the slides anymore. And guess what, If you have a reasonable audience, I probably wasn’t alone.

Last week AdLab did a post about this topic again and posted these 2 color wheels. The first one is the color-wheel as seen by a red-insensitive protopane, the second color wheel is a regular one.

So here’s the normal one:

Now it’s very hard for me to say if the first wheel actually represents what I see, since I obviously see both color wheels different then you, but it should give you a good idea. Also read Paul Martin’s post on color-blindness where you can see a whole lot more of comparison images.
