“Pleasure to me is wonder—the unexplored, the unexpected, the thing that is hidden and the changeless thing that lurks behind superficial mutability. To trace the remote in the immediate; the eternal in the ephemeral; the past in the present; the infinite in the finite; these are to me the springs of delight and beauty.” ~ H.P. Lovecraft
Darkness doesn't exist. There is only light and lack of light.
I find the possibility of physical darkness tempting but what if the concept of darkness does exist in the mind?
Creating darkness and there you have it.
Something parallel to that would be the eight colour of magic. (terry pratchett, discworld) I have thought about it heavily and finally, after much vivid imagination exploration: I find myself gazing upon a colour I have yet to see in this world.
It's nothing but a concept, still very vivid and real to me.
Both darkness and colour X.
If you try enough times, you can bring a dark bulb of darkness into your mind; just switch the machine on.
Sorry if there's no real validity in this answer. Just a view.
