Abstract: A computing device may output content including text content, audio content, and video content according to one or more content output features. The content output features may include font features and page layout features for text content, volume and playback rate for audio content, and playback rate for video content. In some cases, a consumption rate of content by the individual may be determined to identify values of content output features that may increase consumption of content by the individual. The settings for the content output features may be modified to correspond with the values that provide increased consumption of content.

Abstract: A content item to be displayed via a display of an electronic device may be associated with a first set of grey values or a set of color values. The electronic device may generate, maintain, or at least have access to one or more mappings that map the set of color values and/or the first set of grey values to a second set of grey values. Based on the one or more mappings, the electronic device may convert a color value of the set of color values or a first grey value of the first set of grey values to a second grey value of the second set of grey values. The content item may then be displayed utilizing the second grey value.
