Introduction   0:00 Cloudinary can help you to see your images through the eyes of a color blind person, both subjectively and objectively, and provides transformations to make them more accessible. Why you should care about color accessibility   0:19 One in twelve men, and one in two hundred women suffer from Color Vision Deficiency. That's a significant proportion of the population who may miss vital information or are unable to engage fully with your site. Cloudinary allows you to experience all the different types of color blindness, by applying simple transformations. How to simulate color blindness How to assist with color blindness   1:16 You can apply stripes or an X-ray effect to images to help color blind people to distinguish one color from another. ImportassistColorBlind and apply either the xray() or stripesStrength() version of the effect to your image. For stripes, specify the strength of the stripes from 1 to 100: Analyze your images objectively   1:59 The Accessibility analysis feature lets you analyze your images objectively, to determine which of your images may cause problems for color blind people. Set the accessibility_analysis option to true when uploading images to return a color blind accessibility score, together with an analysis of the issues and the colors that may be the most problematic.
