Norton Commander released its blue interface in 1986 (1), when Borland Pascal didn't have released something that had similarities with Norton Commander one year later in 1987, it was Borland Pascal 4.0 (2). And here is Pascal 3.0 for comparison (3).
UPD:
But now I'm not sure that it was NC first. Here is PathMinder (4) from 1984 and IBM FileCommand (5) 1983.
