It would be nice to have the list items color correspond to its text hierarchy. There is the base text size and then the header and smaller size. It would be helpful to differentiate the levels of each item so that it was obvious when something was a sub-item in the list.
Not sure the best way to do this aesthetically. Maybe the header is most vibrant/saturated with each step down becoming a bit less bright. I’m sure there are plenty of ways to do this.
