Abstract: Techniques are described for modification of color contrast ratio based on target contrast that overcome the challenges experienced in conventional systems for color contrast selection. In an implementation, a user leverages a content editing system to select a color set for contrast analysis.

The content editing system, for instance, manipulates color values (e.g., luminance values) of the original color set to increase a contrast ratio of the colors and generate different candidate color sets that are applicable to digital content.
