Take a look at this site.

/P>

One of the mailing lists that I subscribe to provided a link to this site. The subject of the site and the actual content are not all that interesting to me, but what about the color combinations. Much of the material is unreadable to me because of the combinations of colors being used

If I get up real close to the screen and cut down on the ambient light in the room (shade the screen) I can read the text, but some of it is lost. Even the black text on this background is unreadable. How does it look to you?

If you follow the internal links to the dependent pages, membership, etc. he adds a pattern which only serves to make the problem worse.

Comments are welcome. I added your last message to my colorblindness site. Maybe I should add this one as an example of how not to design a site if you want colorblind people to use it.

I got your E-mail with the WEB page included. This is a very good way of demonstrating what one sees. I seem to have no problem reading this WEB page and the other linked sites. I copied a page into PaintShop and tried to change the colors to make the text unreadable, but I am still working on that.

The color change between the background and text appear to be gray and blue. In any case I do agree that the colors chosen are kind of blah. I find it interesting that the text and background kind of wash out together when viewing the WEB page through a red filter.

This would indicate that the site is indeed using blue saturation to differentiate the text and background. WEB pages that use green and yellow or cyan and white give me problems. I'll try and find a WEB page that gives me trouble and send the address to you.
