Color Contrast Calculator


This tool helps in establishing light-on-dark or dark-on-light contrast differences, allowing the selection of a detectable ADA Tile color and a surrounding Concrete color while displaying a percentage of contrast based on the LRV scale. This percentage of contrast can assist the governing body in developing the level of contrast that best meets the needs of the community.
