Everything should be white.

Everything

White, black consoles attract dust.

I always like the original but it'd always be nice if they can input some sort of changeable faceplate just if anyone ever decides to want to change it up.

I prefer black.

I prefer black, but wish more colors were available.

I don't care about the home console colours, but I do like special ones on handhelds with matte materials specially. In a similar fashion also like the controllers to be different. I sold three standard white wiimotes and replaced them with blue, red, black and gold remotepluses.

Consoles, black.
Handhelds white/red/blue

PS2 ruined 150m people clearly, once you go black...

But yeah for me I always go for the original colour of the system, have both a Black and Purple GC tho, but that was its 2 launch colours so it's all good.

White for Nintendo and black for Sony/Microsoft.

Black, because the others colors does not blend with my room.
