We see in darkness.
We see with light.
And as every actor knows …
It is a character.
Don’t get me wrong. Darkness is not the absence of light.
It is its medium. “The light of the mind” they say.
Yes, and its gravity.
And as for colour, well, it is as much a form of darkness as of light.
If you’re writing of the light, and I include the light of the mind and any day on earth, such as this …
… remember that neither shadow nor light came first …
… and you cannot bring your readers to see one without the other.
