Description from store "Colour Blind Simulator" is an extension developed to simulate the effects of colour blindness on a user's web experience, rendering the colours on most web-pages based on a variety of colour blindness templates. It was created with web developers in mind, seeking to quickly check that their sites are accessible to this audience. The extension comes with two modes: "Default View", with just the three main categories (Red-Green, Blue-Yellow, and Total colour blindness); and "Advanced View", which includes all of the variants upon these three categories.
