There’s been no mention of whether white is “universal” or not. But since
it clashes so much with the new permanent colors, I think it’s only a matter
of time before we can kiss it goodbye, too.

I doubt it very much. Natural ABS is a slightly translucent cream color, and
white is probably the hardest color to achieve. Heavy metal pigments are no
longer legal in the US (which is why brown/tan plastic electrical fixtures
are no longer cheaper than any other color), and you can’t exactly combine
two other colors to get white. I’ve never seen a true white ABS. It’s
always slightly warm, and yellows with time. The only way I can see for them
to make true white pieces is to switch those bricks over to a different
plastic, like straight polystyrene. Of course, if we were interested in
buying dirt-cheap plastic with low resistance to breaking, we’d be discussing
this on MUGNET, not LUGNET.

In all seriousness, do you suppose that this is how MEGABLOKS does it? I’ve
noticed for years that their “white” is more “white” than LEGO “white,” but I
never knew the underlying reason.
Is there a simple, reliable way to discern the difference between ABS and
straight polystyrene without damaging/destroying either in the process? They
both taste the same, AFAIK...
Dave!
