dalton: Simulate Color Blindness for Website Viewing

dalton is a free Chrome add-on developed by Jonathan Skeate that allows users to view websites through the eyes of the colorblind. It provides a unique opportunity to simulate four different kinds of color blindness in two different degrees, such as protanopia and protanomaly.

The add-on offers two convenient ways to use it. By default, a popup with buttons appears, allowing users to choose the specific type of color blindness they want to simulate. However, for users who consistently require simulation of a particular type, dalton offers the option to set a default color blindness setting. This eliminates the need to manually select the desired simulation each time, saving users time and effort.

With dalton, web designers and developers can gain valuable insights into how their websites appear to individuals with color blindness. By experiencing the visual impairments firsthand, they can make informed design decisions to ensure their websites are accessible and inclusive.
