CBC: Color Blindness Check
(11-03-2002)
|
|
 For this little tool we got our inspiration from Cal Henderson, who made a page showing the effects several types of color blindness can have on the readability of a web site.
We thought Cal did a nice job and since we are doing two projects where accessibility for people with a disability is a major issue, we thought we might add a little of our own to his work.
CBC is a little tool we made for people to test their webpages with. It re-colorizes any webpage you like into a palette that closely resembles the typical palette available to a person having a red/green color vision deficiency. (This is the most common color blindness. Comparing Cal Henderson's data, it comes closest to Protanopia.)
Below we describe two ways to use CBC.
Both require Internet Explorer 5.0 or more on a Windows PC.
There is some chance that even then CBC will not work... in that case you need to install the latest DirectX drivers.
