Why color instead of just better labels? That's the real question behind a screen like this, not what's on it, but the thinking underneath it.

Reading takes effort every single time. Recognizing a color someone's seen before takes almost none. So on a screen someone's going to open constantly, not once, I'd rather train their eyes to recognize a category at a glance than ask them to read the same word for the fortieth time. The color isn't there to look good. It's there to stop being noticed as a color and start being noticed as an answer.

Same reasoning shaped the progress indicator. Hiding someone's progress behind a tap turns "which one do I continue" into a small research project. Put it in view instead, and the decision about what to open next basically makes itself before they've committed to anything.

A lot of screens get treated as a place to arrange information neatly. I'd rather treat them as a bet on what a person's eyes are going to do the tenth time they open the app, not the first. That's the actual design work, deciding what earns a full reading and what only needs to be recognized.
