This leads me to thinking in terms of an argument in terms of two battling contrasting colors(arguments);contextually...This is a simplistic theory.

One says it's black. The other says its white. So, the two arguments GO back and forth..White black white white black...Like jarring waves. Waves of resonance. Resonance goes bloop bloop splat Splat!

What do we get? Grey, also known as a localized coalescence or pattern of resonance.This is my simple theory. It may be problematic or incoherent--or worse; wrong. But just a little theory. I like the grey area.
