I have 7-8 different colors of bright light orange. When you put any color brick
under UV light, a whole new world can be found. Some glow neon yellow, while
others look dark and brownish. Some even glow neon orange. I imagine that the
lego group can track their production time and location, by observing a brick
under a UV light. I cannot think of any other explanation why there would be
such an extreme variance between bricks which under normal light, all look the
same color. Maybe someone else has an idea. This discovery has caused me to
redo some MOC's, so that there is hidden patterns within them, when you turn
out the lights and shine a black light on them. I am putting together some photos
that demonstrate what I am talking about. It is not easy to do, because the
camera does not always see, what we want it to see. I will post them here once
I am satisfied with the photos.

Presumably it is because they have needed to change the formulation due to availability
of the dyes, rather than doing it on purpose to be able to track when and where
they are made. They can track when and where the parts are made by labelling
and tracking their storage bins, like they do for regular opaque parts.
