How do I test the visual accessibility of web pages under development?

Question

When developing websites, I'd like to be able to quickly switch to "what does this look like to a person with certain types of color blindness?"

I've found Visicheck, which will show you approximations of what an image or a public web page will look like.

Is there something I could use on my local development before a site goes live? A Firefox plugin perhaps?

Answer 1

This used to work on ffx2 https://addons.mozilla.org/en-US/firefox/addon/7313. Doesn't show you what it loks like, but it does give you a table of elements of the site, highlighting those that coudl be problematic.

Why not download ffx portable 2 and install it on that.

*edit turns out a beta of it is available for ffx3
