I mean, for example, I've been always a lover of Nightmare before Christmas, which uses a styling that almost everything is dark, you can see the moon with bats, graveyards and ghosts which is all dark, scary and horror elements but they're not intended to take part from a real horror movie. Yes, Tim Burton works fit very well in this description with NBC, Coraline, Corpse Bride, Dark Shadows...
Another example would be for example the flyers for halloween parties or the horror films for kids, also this image from devianart user that shows exactly what I'm trying to explain:
I'm refering to all this things, the greenish foggy, the haunted mansions, jack o' lantern graveyards and all that stuff that are drawn or filmed in a way that everything makes a scary composition but not to get the people scared, just as an artistic (and usually beautiful) form.
