Graphics, User Interfaces "The color blindness is the inability to perceive differences between some or all colors that other people can distinguish. According to the medical studies, eight to ten percent of male population suffers from some kind of color blindness (figure for female population is much lower). What does it mean to the average Swing developer? Well, if you rely too much on color differences, you may be not conveying the information as well as you thought. Now you can run your application in debug UI mode and have a live preview of your UI as viewed by the color-blind population."

I have been using the Vischeck plugin ( for quite a while to check web page design (and other screenshots) to make sure colorblind visitors can access and navigate the site without issue. The Web Accessibility Initative ( provides additional consideration for accessible interfaces -- even though it is targeted for websites, it is also applicable for other computer interfaces as well.

Oh, THANK YOU! Their example page is something I've been looking for. I have red/green color blindness and whenever people find out about it, I'm always bombarded with questions about "What color is this?" and "What's this look like to you?" That page is a good illustration of the way the world looks to me.

I really see no difference between the "normal" and the deuteranopia examples (except for the hats). I will have to bookmark that page for the next time someone asks.

So nice to see a few "color blind" people "coming out" here.

In the US, there are likely 7 million people affected.

That's a lot of people.

Worldwide, that would be more like 500 Million.

At my office, (I've worked for a very small company for 18+ years.) we've had exactly 1 guy who confided in me. He asked about the color of the wires we were getting ready to crimp.

He also asked that I not tell anyone that he was color blind.

I happen to be gay.

No biggie, there. It's just a fact of life. Another fact of life for me is that I like solitude, and living alone is something I've come to like. Other people are out looking for a mate. I just like being alone. So I'm a gay guy who likes to keep to himself and study Ruby On Rails. ;-)

OK. So that's getting horribly off-topic. Except it's not.

The squeaking wheel gets the grease. And you guys seem rarely to squeak. I rarely squeak. I should squeak more.

I had a client, a few years ago, come to me with a "great idea". We're going to do all this UI thing with color because that's one thing that everyone understands.

I hated it. Not only was it a stupid idea. But I knew how it would affect a significant number of people who don't seem to like to squeak.

So on these articles about user interfaces:

Start Squeaking, People!

It's your interface as much as anyone else's. And the people who are stomping on you honestly don't know they are doing it. And they *can't* unless you tell them.

I truly hope that I have not offended anyone here.

But, by God, you have to let yourself be known or nobody will know you are there!
