Colour-blind friendly Web design
Howard Lake | 1 September 2003 | News
A free online tool will help you check if your Web pages or images are visible to people with colour blindness.
Making Web pages accessible to all kinds of donors requires awareness of how disabilities can affect a Web users’ experience of a Web page. With around one in 20 people having some sort of color vision deficiency, it makes sense to ensure your charity’s Web site is not inaccessible on this count.
A free Web tool called Vischeck is one of several that will help you judge how your page would appear to someone with colour blindness. It offers “a computer simulation of the entire process of human vision.” You can run it online or download a version to run on your PC. You can use it to examine a Web page or an image.

It will reproduce your Web page as seen by someone with one of three particular types of colour blindness: deuteranope (a form of red/green color deficit), protanope (another form of red/green color deficit); and tritanope (a blue/yellow deficit, which is very rare).
The programme isn’t perfect – it won’t work with sites that use an immediate redirect, feature Macromedia Flash, or that use certain javascript operations. But it is available at no charge.
Find out today if your site can be used by someone with colour blindness.
