What does my web site look like to a colorblind visitor?

Thanks to the "Mining Amazon Web Services" book, I cam across this cool web site that simulates how your web page may look to a color blind visitor - it's at http://www.visicheck.com.

Here's a page about our "Of Course" newsletter as it would be seen by people with three different forms of colourblindness.

Deuteranope - a form of red / green colour blindness
Protanope - another form of red / green color blindness
Tritanope - a rare blue / yellow deficiency
Control - the web site as seen by a user with regular vision

In the UK, The Disability Discrimination act requires that providers of services take reasonable steps to make those services as accessible to those with any form of disability as they are to people without the disability. We have a training module available on the subject (it's available for free download as a .pdf too. As well as other DDA subjects (such as font sizes), this module also introduces the UK' privacy and data protection laws and a number of other topics you should be aware of.

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
