Blue mark 6 tenor sax?

i am looking at changing my current tenor sax for a selmer MkVI tenor, i have been told there could be one available but its in electric blue, apparantly selmer made a special edition blue model in its hayday, i know a lot about saxophones, but not that much about this blue model, some say the colour will add value,and others say i'll never resell it, if anyone has any tips or relevant information advice for me i would be most grateful, i am looking for the ultimate stan getz sound,, ( to sound nearly as good as he did would make me one happy lady )
