Abstract
Systems, methods, and computer-readable media for providing tools to validate color contrast are provided. To do so, three discrete color check processes are performed to ensure a user is able to identify when an icon is at risk of being inaccessible by some users. A border score considers each pixel at the edge of an icon compared to the background in which it is placed. An area score considers each discrete pixel of an icon compared to the background in which it is placed. A grid score considers a subdivision of an icon compared to the background in which it is placed. Using each of these three independent process, a summative score is provided. The summative score categories the icon into a risk level. Depending on the risk level, the icon may need to be refined to ensure it becomes more accessible.
