Applying Color Theory to Digital Displays

Selecting the right text and background color ...

"This article is Part III of my series “Color Theory for Digital Displays.” It describes how you can apply color theory to application program user interfaces and Web pages and provides many guidelines for the effective use of color.

Ensuring the Readability of Text Through Contrast
For backgrounds behind text, use solid, contrasting colors, and avoid the use of textures and patterns, which can make letterforms difficult to distinguish or even illegible. Choose combinations of text color and background color with care. Value contrast between body text and its background color should be a minimum of about eighty percent.

Contrast With a White Background
Black text on a white background provides maximal value contrast and, therefore, optimal readability for body text. The contrast between charcoal gray (#333333) text and a white background is about eighty percent—thus giving minimally good value contrast."    (Continued via UXmatters)    [Usability Resources]
