Lack of Color
Challenge explanation by anecdote:
When I was a kid, I thought that the reason all older movies/ shows were in black and white becuase that is all people saw in. I though that we had evolved from dogs, and only fifty years ago, everybody, humans and dogs alike, saw in black in white. I learned differently, of course, but that thought has stuck with me for years.
Your challenge is to write a black and white story. The possibilities are endless really. Maybe only you see in black and white. Or everybody does. Maybe even everything really is black and white. These are just my suggestions.
But there ya go. You have more than a month. Chop chop.
If you need clarification, note me or just post your question below.
Read it. Write it. Love it.
