Avoiding the debate over the color change, I want to bring up another issue. It
is quite obvious to me that modern Lego pieces are much more translucent than
the old ones. I might be speaking about ancient times which nobody cares about
here, but all my old pieces (from the "Pat. Pend." era into the 80's) are
distinctly more opaque than all my new pieces. I can easily tell the difference.
This is not only due to the thinner walls of some new pieces. Even walls with
comparable thickness are quite different in opacity.
The light from a small flashlight can easily be seen through the new pieces.
This is certainly not the case for the old pieces. (If I weren't set on avoiding
the new/old grey issue, I would make a silly pun and call the modern red "bled"
because light bleeds through it.)
Did the recipe for the ABS plastic officially change at some time? Does anyone
even care about these things, or has my job as a color scientist influenced me
too much, and I should get back to building instead of looking very closely at
my bricks under a flashlight? :)
I don't really find this disturbing, but I am curious about when and why it
happened.

| (...) I don't have much to add here except to confirm that I have seen this as well, older ABS is less translucent than newer ABS. It may be an attempt to save on pigment rather than an ABS formula change. It may not have been a sharp break point (...) (21 years ago, 11-May-04, to lugnet.color)
