Colour Contrast Analyser for Web Pages What is the Colour Contrast Analyser?

A colour contrast analyser that examines the foreground and background colours of text nodes, and provides a report to see if they are correct according to AERT and WCAG's luminosity colour contrast algorithm.

What is the Luminosity Contrast Ratio Analyser? It is primarily a tool for checking foreground & background colour combinations to determine if they provide good colour visibility. It also contains functionality to create simulations of certain visual conditions such as colour blindness.

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.
