Where to use color:   Text – Background- Images

Why use color:  Attractiveness – Information

Should the use of color be avoided altogether?  No... Color is one way to provide information but not the only way; information should be provided in a non-colorful manner.  Use font, special characters, or other context in addition to using color.  Contrast between font and background color should be considered.

Content Management System such as Blackboard and WebCT allows developers to choose text and background colors.

 

More Standards for color WCAG 2.2:  Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits or when viewed on a black and white screen. [Priority 2 for images, Priority 3 for text].
