Hi,
We just received a new rev of a PWB in house.  It has not been populated
yet.  It looks like it has been built correctly - the right layer order,
connections, etc - but it looks different than the rest of our 4 layer
boards.  Normally the traces on the inner layer that is closest to the
surface appear dark in colour and the deeper layer appears lighter.  This
board is the opposite.  The layer closest to the surface is light in colour
and the deeper layer is dark.  Also, the FR4 seems much easier to see
through than usual.

Any thoughts or explanations for this?
Thanks for your time.
