[Jason Whiteman <whitemanjason@xxxxxxxxx>]

In my unreleased (due to incomplete status of the entirety of changes I was
working) soldermask arbitrary color / silkscreen arbitrary color
enhancement - I noticed that the soldermask bottom side obstructed traces
so I had to adjust the transparency until both sides were balanced.  I
didn't spend much time trying to determine what the root cause was - but
did verify that layers were balanced and I added lighting to try to change
the behavior with no reasonable results whereas transparency seemed to fix
whatever the root cause was.

I cannot get to the build server at the moment but would be happy to trade
notes.

Regards,
Jason
