Main Document

Color codes present particular problems for color blind people as they are often difficult or impossible for color blind people to understand. Here is a color spectrum chart for website and page design for persons with color blindness.

Website Design Implications of Color Blindness

Color codes present particular problems for color blind people as they are often difficult or impossible for color blind people to understand.

Good graphic design avoids using color coding or color contrasts alone to express information, as this not only helps people who are color blind, but also aids understanding by normally sighted people. The use of Cascading Style Sheets on the Internet allows web pages to be given an alternative color scheme for color-blind readers.

Web Page Design Tips for Color blind Users

Red and green can be hard for a color blind person to tell apart. Avoid placing red and green colors together.

Don't use only color to highlight something specific on your web page.

De-saturate web page images to see if they still have impact.

You could also use the color chart to find ideal coordinated color schemes and palettes that complement one another for website themes and designs.
