I think the Switch dock is ugly & that is pretty typical of first-gen Nintendo hardware.
So any colour they use is way back of the priority list to me. I'd much prefer redesigned hardware with more curvature and less 'squarevature'.
With that said, in general I like console colours that stand out from the typical boring TV / Blu-Ray / DVD electronics.
I'd much prefer bright yellow or pink and definitely prefer orange or white/beige above any of the typical 'male' blue/black/green/grey choices, which we have been so conditioned on they make me sick.
I think that Nintendo chose 'boring' to appeal to most adults conditioned on 'boring' with that colour being the one that would be 'safest' to appeal to both males and females without creating too many notable aversions or divisions of opinion. In other words it is 'safe' and 'boring' for both sexes conditioned on boring, particularly adults who are all well down the path of colour-conditioning. Matte has finally returned which is well overdue. Don't get me started on gloss surfaces on so many electronics...just don't.
