I
just traded my 09 white diamond CTS for a 14 white diamond CTS. I could swear that the colors are not the same. The 14 is more white if that makes sense. Anyone else notice this difference?

Yes, I think your right

I think the base color is arctic white, don't know what it was in 09.

I think that newer White Diamond cars usually look whiter than
older. Could be weather, how maintained, garaged, etc.

I also feel that with the 3 layer paint, that White Diamond cars
of the same year also vary some and some are whiter, while
some have more yellowish.
