color-challenged in Flash: Part 3

Over the years, I've informally explored the issue of color-challegned users in Flash. Some of my recent explorations have turned up these links:

And here is a book I'd like to pick up:

GalaxyGoo Going CSS

After five years as a table-based website, GalaxyGoo will be converting to CSS for layout. The conversion is quite a bit of work, I'll tell you. But it will be worth it once it's done. Already, it's getting easier.

Why did we wait so long? I was concerned about older browsers being able to use our site. Believe it or not, Arpanet shows up in our logs. But the simplicity and separation of content from presentation was too much for me to resist.

Color-Challenged in Flash: part 2

There's been some talk about about color-challenged design issues, in blogs recently. This has inspired me to dig out my explorations with flash and how colors may be perceived with some types of vision.

Color can be a powerful tool for communicating and visually organizing complex data and illustrations. It can be especially useful to highlight a small portion of a larger image. But if these colors are difficult for some users to distinguish, the effectiveness of the tool is lost.

So, I've been toying around with adding custom color choices to Flash projects. I began tackling our HIV animation, because it uses green as a significant color. But this is a big bite to chew, so I'm starting a little smaller. Here's a simple simulation with custom color options. I didn't put a lot of thought into the custom colors--just picked some colors from the translated color-chart for each vision type, that seemed to have at least a little contrast.

If the developer has kept color definitions encapsulated, it should be easy to "redefine" the colors and offer a user interface to select a palate for their vision type. Older, frame-by-frame animations can take some time to go through and set up for easy color definitions with code. There's got to be an easier way to do it, but I haven't gotten there yet.

It would be nice if there was an easy way to pull the hand-set color definitions out of a file, and add new definitions with code. Maybe an extensibility project?

Web Content Accessibility Guidelines 2.0 Working Draft

The W3C has published it's working draft for Web Content Accessibility Guidelines 2.0.

After a quick glance, I can't help but think that with Flash breaking out of the browser, we should pay close attention to guidlines on functionality: keep it operable through a keyboard or a keyboard interface.
