Shift colors to make text and images visible with certain types of color blindness
This feature allows users to (via installed software or online services) convert colored text and images so that colors are distinguishable to those with certain types of colorblindness. For example, a site with green text on a red background may be very difficult, if not impossible, to read by someone with red-green colorblindness, but a simple conversion to green on white could solve the problem.
