No, it's grey. This is a feature in the Note Tabs plugin: Plugin: Note Tabs
I think this plugin will resolve this issue for you, as well as resolve an issue you didn't even mention since it's super convenient to be able to pin notes you're working on, separately from Favorites. E.g., I use Favorites for notes I always want to have close at hand, but I use Note Tabs to pin notes related to whatever project/multi-faceted tasks I'm currently working on; these get swapped out as one project is completed and another project started.
