I can't be sure from one photo -- but so far, I like the blue you chose.
It appears to be a shade darker than the dominant playfield light blue, and a bit less red and dark as the ominous blue in the BG, but perhaps matches the plastics and apron quite well. Makes sense, to be pick something between the extremes of 4+ different blues on that overall composition -- no easy decision to make. (Meanwhile it has to balance with the orange as well...)
