If you using local color in an unobtrusive way, it is all for the good. But if you stress it, the whole thing is artificial. But it should be used, I mean, it's not forbidden. But you don't have to stress it.
Jorge Luis BorgesDo you want to see what human eyes have never seen? Look at the moon. Do you want to hear what ears have never heard? Listen to the bird's cry. Do you want to touch what hands have never touched? Touch the earth. Verily I say that God is about to create the world.
Jorge Luis Borges
