Clear is 1000% the best option.

"Owning a yellow robot might be a sign of chinese slavery"

I read recently that white plastic was the more expensive color to produce. I wanted to cite/link a source but internet search is frustratingly bad these days.

Edit: Not quite what I read but close enough.

Yellow robots would be very problematic

no, white is best.

when the robot rebellion comes, and they are hunting us at night, I'd like a fighting chance to see them coming.

edit: I said what I said.

Also, last I checked white people weren't literally white as freshly fallen snow. The robots aren't caucasian flesh tones.

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.
