Color Accessibility

Guidelines for Choosing Colors

Choose colors that work for everyone

• Provide sufficient color contrast
• Do not rely on color as the sole means to convey information.   Add another visual element to indicate meaning, such as an underline or an icon.


• Increase your audience
• Low vision, color blind, and aging persons can access your content
