I just had my first 787 experience (and was very happy with it!).
One thing I noticed about the interior lighting system is that there seems to be two sets of LED's mounted above the bins. One of them projects one color at the ceiling while the other projects a different color at the opposite bin. Thus, the ceiling will be illuminated in blue and the bins in white. Or for sunrise, the ceiling was purple and the bin was yellow-orange. I was very impressed by the system.
Does anyone have any schema of how this is accomplished? I found it amazing that while the light was aimed at the bins, it was impossible to see the LED strips from a seated position.
