You weren’t originally designing with colorblindness in mind, but now your app isn’t useable to everyone. “Everything is there, you don’t see it?” Your coworker quickly realizes what’s going on, “I’m colorblind-I bet the colors don’t have enough contrast, so it looks blank to me.” However, you notice that one coworker looks puzzled: “Where’s the content? I don’t see any text, it’s just blank.” You anxiously take a peek to check what’s happened, only to discover that you can see the text. You’re excited to share your brand-new, fully styled app with a coworker and you wait eagerly for their reactions as they click through. Your new app looks super sleek, with a white background and light gray text. Let’s imagine you just finished building an app-an app that helps keep track of projects and the documents associated with that project.
