Do I edit the old reply or post a new one? Well, for everyone to see my errors I will leave the previous post up.
Talked with an experienced 737 driver who flew the airplane for different air carriers, his response was "If you have an engine failure, the light gray panels will all need timely attention. They are not "memory" items, but will be addressed in the checklist." They are not used for anything special by his company, maybe the gray panels are used by some other airline for a useful purpose.
I certainly apologize for spreading the previous misinformed rumors, I thought I knew, but I didn’t.
