Dim, murky lights, despite how little or how much heat they may generate, look warm to me. They emit a sense of coziness. Yellow and orange hues of incandescence feel familiar and comfortable to us. But then, the bright fluorescent bulbs and tubes we surround ourselves with look cold. The photons from those lights harshly sting our eyes. They have no capacity for familiarity or comfort -- they are strangers.
I'd rather sit with you, beneath incandescent lights and a warm blanket, than with strangers in a storm of icy eyes and cold shoulders.
