When it comes to grey it all seems quite simple to me. Strictly speeking grey is
something that uniformely reflects all the light in a visible range regardless
of a wave length, say it reflects 30% of red, 30% of blue, and 30% of green
falling on it for some darker shade, or 70% of all for a lighter shade. Here on
one end we have black (0%) and on the other end we have white (100%). Anything
that fails to reflect light to equal proportion can't be called grey. The old
grey of Lego is by far closer to true grey than the new one. For this reason the
new grey can be called whatever but grey. Call it stone or bley but we don't
have true grey now. Pity, cause the true grey is quite neutral and is good fit
for almost every other color.
Now imagine a 3D coordinate system with R,G,and B assigned to axis. Let's have 1
for 100% reflection on each axis. At the vertexes of the 1,1,1 cube we will get
Black (0,0,0), White(1,1,1), Red(1,0,0), Green(0,1,0), Blue(0,0,1),
Yellow(1,1,0), and also Cyan and Magenta. The shades of grey will fall onto the
straight line connecting 0,0,0 and 1,1,1. I guess existing red, green, blue and
yellow of Lego come very close to those pure colors. This makes blue perfectly
match yellow etc. If anything can be called universal, those colors (including
true greys) are. Other colors can represent some natural materials such as wood
or stone but they are not that basic as say red or true grey.
Now to explain the yellowish cast on white bricks placed along with the new
"grey". You must be aware of white balance issues with digital cameras when
under different lighting conditions different correction curves have to be
applied to images to compensate for irregulariry of the light. The human
eye/mind tends to automatically adjust to the lighting condition so we don't
have white balance issue to such extent as cameras do. I guess human mind takes
some average color of the scene or takes some basic colors for basis. Now we
know that the white and the true grey are perfect match as they reflect light
uniformely in the whole visual range. Now if we put some small amount of blue
into grey and still take it as a basis for our white balance (pretend that it is
grey) than white becomes short of blue to match the new grey, that is it has
excessive red and green making it look yellowish (r+g=y or w-b=y).
That's how near to grey colors can fool our white balance system.
I bet that one day in future TLC will go back to true grey shades as they are so
fundamental for the color system.
