Accommodating the Color Blind Online
Web sites with good balance and color schemes have the usability and appearance. Similarities in hues and brightness harmonize colors and create attractive color schemes. However, they’re not “user-friendly” for the visually impaired. Nearly one in 12 visitors to your site will have some form of color-blindness. Most commonly, the inability to distinguish between red and green. So a red-green combination is a bad choice for usability. If links are a different color, but aren’t identifiable as links, color-blind visitors may not realize that they are links. Blue is recognizable by everyone, and the standard usage of blue, underlined lettering for links gives all visitors the same usability.
With all colors, it’s best to keep them bright and distinct to clearly separate headings, links, and text, and increase functionality.
Use the following links to help choose your winning color schemes.
Give thought to what emotions your colors will trigger, and how the colors enhance your site’s usability. When you consider your viewer’s needs, select a color scheme that is appealing, and is easy for them to use, you’ll have the winning edge to convert visitors into customers.
