Red Stripe is great if you have difficulty seeing certain colors. It helps people with a red-green color blindness distinguish yellow, red, purple from other colors by adding a stripe pattern over those colors. The stripes becomes more pronounced the higher the red component in the color, so a dark or grayish red will have darker stripes than a highly saturated red. Stripes also appear with various intensity in other colors that have a red component, such as yellow, orange and purple.
Red Stripe displays a floating window showing live what’s underneath with the stripe pattern overlaid. This allows a red-green color blind person to differentiate colors on websites, pictures, and documents with more ease. You can also interact directly through the filtered view with the windows behind.
