Thanks Lou. I didn't know about Millie Small's passing. That was an iconic song.

Thanks also to gillymor for your magnanimity. Wayne Newton, hmmm??!! Now that you mention it.

Back to the topic: have we agreed on the three possible and probably real meanings of MBL? (Real as opposed to being funny/clever but silly.)

Nick said metallic blue, Reinhard said matte black or metallic blue, and Mick Pearce said marine blue. So it is used differently by different guitar makers.
