It was just a joke about office lighting ;-)
The only way to know the color of a bulb is to see it or at
least get a view of a graph of it's output across the
spectrum. Color temp ratings are like a can of beans for
dinner. It passes but far from ideal.

I like 6700K on planted tanks, I wouldn't consider it
blue at all. It is
more of a yellow. I also keep reef tanks and prefer the
14,000K on those.
10,000K is pretty much stark white while 14,000K has a
fair amount of blue
in it. I have never heard of offices with a blue color.
Most cheap
fluorescent bulbs used in offices use the cheapest
phosphors available and
are pretty yellow.
