We ordered dark bamboo flooring for our entire house except bathrooms....and very light blond bamboo flooring was delivered. The company acknowledged the mistake and asked if we were interested in keeping the flooring at a discounted price. We decided that the price was too good to pass up.
We love our blond floors! I run a sweep vac through the house just about every day (no more than a 15 min middle of the room kind of thing) and my DH mops once a week, but dirt doesn't show up badly at all. We have 2 very active, dirty boys and an inside/outside dog.
I know it doesn't answer the original question, but maybe it will help your decision.
