About AccessColor AccessColor tests the color contrast and color brightness between the foreground and background of all elements in the DOM to make sure that the contrast is high enough for people with visual impairments. Assuring that you provide enough color contrast between foreground and background colors takes time and we hope that this tool will help web developers to build accessible websites by visually flagging the section(s) of a page with problematic color combinations. AccessColor will find the relevant colour combinations within your HTML and CSS documents rather than requiring you to find each value to input yourself in order to test the contrast between each colour combination.
