2. Don’t rely on color alone.
Ensure that text and graphics are understandable when viewed without color. If color alone is used to convey information, people who cannot differentiate between certain colors and users with devices that have non-color or non-visual displays will not receive the information. When foreground and background colors are too close to the same hue, they may not provide sufficient contrast when viewed using monochrome displays or by people with different types of color deficits. Checkpoints:1. Provide alternative content.
Guideline 1. Provide equivalent alternatives to auditory and visual content.
Provide content that, when presented to the user, conveys essentially the same function or purpose as auditory or visual content.Introduction to Accessibility

Cascading Style Sheets description from the W3C
Cascading Style Sheets (otherwise known as CSS) is a simple mechanism for adding style (e.g.fonts, colors, spacing) to Web documents.
CSS is formally described in two specifications from W3C: CSS1 and CSS2.
CSS1 was issued in December 1996 and describes a simple formatting model mostly for screen-based presentations. It has around 50 properties (for example color and font-size).
Images not visible in a Drupal Version 5+ Installation? Here’s one solution which solved the problem for me.
The Drupal (CMS) uses .HTACCESS files to control directory access (unless of course you override/remove them and control your settings with modification to your PHP.INI file). On first install of this site I noticed that uploaded images were not visible in the default installation. The way around this is to use the following piece of .htaccess script in the folder where the images are kept on the server. So upload the following script to the offending folder and the images should become visible.
