Perhaps the being mode may best be described in a symbol suggested to me by Max Hunziger: A blue glass appears to be blue when light shines through it because it absorbs all other colors and thus does not let them pass. This is to say, we call a glass 'blue' precisely because it does not retain the blue waves. It is named not for what it possesses but for what it gives out.
