Chromatic Vision Simulator is an Indispensable Tool for any Educator Professor Asada did the world an enormous favor by creating this tool. All educators at any level should download it immediately and show it to their students. It shows the instant impact of colour design, on how teachers use the whiteboard / chalkboard and presentation materials. By using this app, you can prevent making resources which are ambiguous or confusing. If your organisation has any “Alert/Emergency” resources, take a look at them through this app and see if they really are functioning as alerts. Inclusive design starts with all of us. Download it today! Plus enable screen colour filters if needed.
