I just realized as a result of this discussion; most consoles these days seem to come in black and maybe white. If they come in any other color, odds are, it's a limited edition. And as time goes on, even that isn't guaranteed.
I'm sure I missed something, but that's what I see. It's not any real issue, since these days, I'm happy with any color, but I do admit, as much as I would have liked a pink PS4, it'd look odd and silly. Like me.
There are console skins, but still. Probably more cost effective, and I suppose I don't recall many colors of consoles, but I admit, there seemed to be more variety between competing consoles, and now it's black or white regardless.
I'm glad some companies' controllers still have variety to them, though that's probably more out of necessity (since many controllers are wireless these days).
The Switch seems to be more gray...which is still more monochrome than blue or purple or yellow. Or green, red and pink.
