It was a very moving experience because the exhibit was not very large, but the power or the space was emphasized by the deep greens, natural wood blondes and glass casings with sparkling dimly lit halogen lamps. It felt like an orchestration of light. Most Americans live in white rooms. White is an easy color to live with, and because of its neutrality there is an infinite possibility of style and shape that a room can take without being destroyed. Richard Meier based his entire oeuvre on white.
Geometry plays well off white because corners and curves are better marked in direct sun lighting.
Of course with floodlights and interior lighting techniques, it is possible to experiment with illusion of space, even sticking to white. I found that even in parts of Europe white is a preferred color. With the sticky climate of Greece for example, especially in Athens were the air doesn't tend to move at times, white suites the means of keeping cool very well. Reasons for using color should not be limited to psychological factors alone. In the case of the white washed homes of the Greek isles, a physical barrier is formed between the blistering hot sun and the inhabitant inside.
