There is a brief period of twilight of which I am especially fond, little more than a moment, when I see what seems to be color without light, followed by another brief period of light without color. The earlier period, like a dawn of night, calls up such sights that at all other times are hidden, wistful half-formless presences neither of day nor night, that draw up with them similar presences in the mind. ~ Robert Grudin, Time and the Art of Living
The blue hour--my favorite time of day.
