- Vischeck (http://www.vischeck.com/vischeck/)
Vischeck is a way of showing you what things look like to someone who is color blind. You can try Vischeck online- either run Vischeck on your own image files or run Vischeck on a web page. You can also download programs to let you run it on your own computer.
- WAVE (http://wave.webaim.org/)
The Wave accessibility checker makes use of graphic symbols to help alert you to accessiblity errors in your webpage. In general, the Wave will not tell you if the page is accessible. It's impossible
for any tool to perform a completely automatic check. For example, a tool
can check if ALT text is present, but it cannot tell if the text is meaningful
or useful. You must exercise judgment to tell if the page is accessible. The
Wave gives you information you need to help make that judgment. One especially nice
feature is that it analyzes the reading order of a page, so you can tell in
what order your page would be read.
