Daylight remembers where it has been; it always arrives with company. It reaches us most evidently accompanied by heat and color, which derive from its source, the sun, and from surfaces it has touched on the way to our eyes. We can see and feel heat and color quite easily and both are capable of influencing our perceptions and our use of space. Daylight levels and character, including color and motion, often signal to us what the temperature of a place is before we are close enough to feel heat or cold. It has been noted that sight may be considered an extension of our sense of touch, enabling us to understand, at some distance from them, how things feel. The understanding is based on our knowledge of having seen and touched these things before. In this way, daylight messages engage our individual memories. What we see and what we know about light leads us to anticipate the character of a space or a surface and to draw associations with other times and places. Associations between light, its source, and events on the way tour eyes stimulate our own deeply held associations.
