    As one of the afflicted I enjoy the dialogue on how to make our lives easier.

    For regular text like the above I'm ok with the color deferentials, but I suspect the added font hint would be very helpful if the black and reds were indistinguishable. A subtle clue that's highly readable and clearly different.

    Might the font changes be a little too chaotic for the general public who don't need the assistance?

    I for one, find it convenient to read.

    Akimbo, if you use firefox there are several browser plugins that attempt to simulate color blindness for the benefit of web developers dealing with this situation. They'll allow you to easily tell what will be bad for a color blind viewer.

    Also, most browsers support "high contrast" mode in their accessibility options that will override the colors presented on a web page with high contrast (e.g. black on white). Regardless of what a page was coded to use. In firefox you click Tools -> Options -> Content -> Colors. It defaults to "follow" the operating system's setting for accessibility, but you can change it to "always" if that's not working.

    Thanks for the input. Should I start a thread with a poll and the samples above, or would that be too carried away?

    Very cool, I had not heard of that. Is it anything like this simulator? Coblis Color Blindness Simulator

    Also a great tip. I wonder how many people know about it? I hope that tip helps some divers here.

    I’m kind of late to the party here, but since I was called out upthread I will note that we did a lot of consulting with a color scientist in the course of developing the Cobalt’s color screens, and used tools to simulate various forms of color perception differences when designing our displays. It’s an interesting and complex subject. We made a lot of changes based on what we found, and later on feedback from the field. Color, contrast, and luminance all enter into legibility. Red on black is an obvious problem that I see being used on displays very frequently. Yet it’s possible to come up with something that most people will interpret as red- for it’s common alert significance- while, for instance, including enough yellow and luminance that it pops from the background for those with red color perception issues.

    While we have tried to accommodate the most common forms of color perception variation, its probably not possible to both use color and have a single ideal solution for everyone. But it should be possible to design displays that are legible and don’t have elements that disappear for some users.

    This thought came to mind and is mostly a question the moderator code gurus. Would it be excessively difficult to make viewing styles for color blind divers? For example, display red in green or yellow for divers who can't see red?

    In an ideal world, Microsoft, Apple, and Google (Android) would add the feature to their operating systems.
