Ripley is an adaptable typeface with multiple axes designed to optimize on-screen legibility. It combines historical and contemporary shapes to create a new serif design that serves as a toolbox for readers. In addition, Ripley changes by reacting to the ambient light. It thus adapts to the time of day and the light available in order to take into account that a reader’s eyes might be fatigued by the end of the day. Evolving thus throughout the reading experience, it strives to provide the best possible on-screen legibility.
