The Trace Center has some cool stuff dealing with assistive technologies.

British Telecom's site on colors has a nice page that shows all the "normal" colours in relation to the 3 different types of color "blindness."

Just adding to the links.

This is the kind of tool that comes in really handy for organisations like my own (the BBC), given that we're responsible to a license-paying public, and have to make sure our material complies with accessibility guidelines.

Thanks for the link! I ran all the sites for which I'm responsible (including CharlesDaly.com), and they all did fine ... which was dumb luck, believe me.

Again, thanks. This link's a "keeper".

the link doesnt work

05 Mar 2003 | matt said...

The link works again.

While I was vacation (just got back a few hours ago) my ISP shut down the script due to excessive load on the server. I need to investigate, but my current operating theory is that someone may have been abusing the script (automating a download of some giant collection of filtered pages).

Or maybe there was just a lot of traffic going through the site..?

the quick version for people with IE:

Grayscale test

This link should grayscale the page through javascript. You can add the link to your bookmarks and then execute it that way. Adding to favourites or bookmarks will get a security warning because the link contains javascript, but it's safe, it's just applying a quick filter to the page) :)

That's neato, Paperhead. Are there many other filters like that for IE?

I've been doing some research of this topic for about 12-15 months now and I found this post quite interesting.

I'm currently a Masters student in Interactive Multimedia in Sydney Australia and I'm researching and designing with this topic in mind, I've posted a url to a ton of links I have on the topic of Colour-Blindness and technology use, in particular new research in Mobile and PDA use, future colour use, etc.

Note this site is still in development and will launch soon. (excuse the mess :)

there's a fair few of them Joshua, glow, flip horizontal, flip vertical, alpha opacity and such. if you use CSS [and who doesn't nowadays] you can just throw one line of code into the stylesheet to get a cheap effect for IE without buggering up the other browsers that don't have support for such filters (though you can get opacity in Moz/MM6 throught moz-opacity. throwing them into a link just means that they execute through the address bar, they are commonly referred to as bookmarklets [or some people call them favelets]. a quick search of google for bookmarklets and accessibility should produce a fair few finds. from what i know, they were pretty much invented single-handedly by a nice man called Steve Kangas at bookmarklets.com. Most of the ones on his site are designed to either empower the user [user-defined hyperlinks] or to help accessibility [there's a brilliantly scripted one that throws up an array of all 216 safe web colours]. one of my faves for this kind of thing is bookmarklets that help level the browser field, so as Opera lets you zoom the page and NN/Moz lets the user increase the text size regardless of page settings, so you can run these on the later IE:

+ + + - - -

sorry Joshua, that probably far more than you wanted :)

by the by, i don't know if you'll still be able to find it anywhere, but there was a very interesting little browser out there called pwWebSpeak 32 that lets you browse pretty much text-only, but reads the pages out to you in one of a variety of voices. it's something that really makes you think about how you order the flow of your pages structurally. this is also pretty interesting over at W3Schools.

it seems the colorblind colorfilter just got too popular. I've hacked off a bunch of features to hopefully make it less of a server-hog. We'll see if this stripped down version can avoid being killed by the sysadmins.

Nice blog I am glad to see

For example, if you see an AIM window peeking out from behind your browser and you click on it, that window will come to the front, but the main application window will not. The Mail.app/Activity Viewer is another example. The Aqua system of layers works well in many instances, but not in all. Thank goodness that the Dock is always there to come to the rescue. I know that clicking on an application icon in the Dock will always result in not only the application coming to the front, but also any non-minimized windows associated with it. And if the application is active but no windows are open, clicking on the Dock icon should create a new window in that application.

This topic is one we will tackle later in this article, but it refers to making sure that your application and the dock aren't fighting it out for supremacy of the screen.

At WWDC, I listened to Apple representatives make some excellent points about taking the time to build a 100%-compliant Aqua application, and I think all developers need to look beyond the code and listen to what the folks at Apple have to say
