I don't think so, but from a consumer point of view, white appliances and wood panel appliances were the industry standards for kitchen and laundry vs home electronics like TVs and radios, in the US a white appliance is usually more expensive but more reliable than a wood paneled appliance, but people also see chrome and black appliances of all kinds as more modern and top of the line, these are very intentionally establishment aspects of product colors in US retail, so if the robot is white people tend to think 'pricey but well made' and a black robot as 'modern, up to date with lots of features' at least that's my experience from being in retail sales for years.
