Uh thanks for the rather thorough answers. The TV safe white I have found is a Neutral gray or Dove Grey. They just needed to be on the lightest side of the ten shades of gray that video produces.
They both look great, they get rid of the noise, they still look white to the facilitators and it solves the over exposed row of nameplates.
TV WHITE = 60% reflectance
TV Black = 3%
I also did a wet sand on the plexi cardholders and no more glare, my first idea of hair spray (streaks and tips) got a few laughs.
Sometimes the best solution is the most simple 🙂
Cheers
PS In my Google search for TV White the TV white safe zone has become an engaging development. Heaven help us!!
Who ever said air was free??
