Low Vision Custom Color Settings
Some users with low vision can see content more easily if the default colors are inverted (white text on a black background), customized user styles are applied (blue text on a yellow background, for example), or a custom color scheme is used. This can be done using the operating system, with screen magnification software, or with user style sheets in a web browser. To ensure web accessibility for these users, make sure your page colors have sufficient contrast, that color is not used as the only means of conveying information or meaning, and that colors are specified for page elements (typically using CSS to at least define the page foreground and background colors).
