Techniques are provided for selectively and dynamically determining one or more words of an electronic book to present with comprehension guides. For instance, an electronic device rendering an electronic book may determine whether to display some, all, or no words of the book with comprehension guides for words within the electronic book based on word difficulty, contextual importance or aspects of the user. Techniques are also provided for determining the content of comprehension guides to be presented with the words.

Selective display of comprehension guides

Systems, methods, and computer-readable media are disclosed for dynamic color adjustment of electronic content. In one embodiment, a system may determine a first background color corresponding to a color theme for use in presentation of electronic content, the color theme further specifying a first text color for displaying text. The system may convert the first text color to hue-saturation-value (HSV) color space, and modify a brightness component of the first text color to generate a second text color. The system may determine a first contrast ratio between the second text color and the first background color, and determine that the first contrast ratio satisfies a first threshold contrast ratio. The system may display the electronic content using the first background color, the electronic content including text having the second text color.
