Accessibility & Ember: Learning about Colorblindness by Agathe BADIA How do colorblind people perceive colors? How many types of colorblindness exist? How can we help as developers? There are many things we still don't know about it, and bad practice is very common online. In this talk, I will share my learnings about colorblindness, share my emulator project and its outcomes. Hopefully, to spread awareness and improve the experience of colorblind users. Because accessibility is everyone's matter :)
