Creating Color Blind Friendly Web Pages
Creating a Web page that is accessible to color blind people can make a big difference in how your pages are perceived. As much as 12% of men in the US are color blind, and if your pages don't reflect that, they might not be seeing your pages at all.

However, even with the most flexible layouts, there can be problems when the reader zooms in using the Web browser. So some designers developed the idea of creating alternate style sheets that were written specifically for low vision readers.
