Purple avenue in Monopoly (6)

I believe the answer is:

baltic

(Other definitions for baltic that I've seen before include "Scandinavian sea" , "Sea in N.Europe" , "Sea of northern Europe" , "Nearly land-locked sea of Scandinavia" , "Northern European sea" .)

I've seen this clue in The New York Times.
