Using a black cream shadow as a base is really going to make that purple pop. I’m using a MAC Paint Pot in Blackground. Just paint it into place in the general shape of your lid. I take mine slightly higher because I have very little lid space. If you also have small lids, take a look at yourself in the mirror looking straight ahead. If you can’t see the shadow in your crease at all, take it just high enough that it shows.
