Color-blindness
You are currently viewing the page as a color-blind user might see it. Color blindness is a vision anomaly that prevents your user from perceiving certain colors. There are several types of color blindness; here you see the page under a protanopia spectrum (the user does not detect the color red), but some users may not perceive green, blue or any of the three colors. An estimated 45 out of 1000 people are color-blind. To ensure that your site can be used by people suffering from color blindness, remember to check on your applications that the information is not conveyed solely by images.
