As you are creating a Seed site, I recommend setting the admin panel colour scheme to Sunrise (it's bright red). This can help prevent mistakes in the future.
Later, when you're using the Seed site to spawn another new site, you can minimise the chances of getting the two sites confused by making sure the Seed site is extremely noticeable. By making the Seed site's dashboard standout confusion is less likely. You do not want to make unwanted changes to your precious Seed site.
So set Sunrise to be the colour scheme for the admin user on the Starter site. And while you are here you will also want to straighten out the First Name, Last Name, Nickname and Public Display Name associated with the Admin user.
Later when you use the Seed site to create a new site, make sure the first thing you do is to change the admin dashboard colour scheme on the new site to something other than Sunrise. That way the Seed site will always stand out and you won't get it mixed up with something else.
