Nothing makes an expensive piece of equipment look cheap faster than dust.
There is a large market of women who will be making purchasing decisions. Most of us pick light colors because of the dust and cleaning factor. I have noticed that the 'start' button on appliances usually say 'start', but on electronics targeted toward men they say 'power'. I think if companies want to open a new market, they should target the women which would mean lighter colors. Beige is fine with me.
