Welcome to the Color Laboratory For those who have been here before, or who prefer to read documentation only in emergencies, begin by using the controls in the frames directly above. The colorpicker to the upper left will allow you to add color swatches. If you would like to see your own web site through color blind eyes, please try the web page color filter, currently in early development. Your feedback regarding the colorlab and/or color filter is appreciated. Please email aware-colorlab@hwg.org.

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.
