Many options would work in my opinion:
Easiest/Least Maintenance: Black/Black
Hard to maintain, but would look good: White/white
Compromise: White tape/Black saddle (reverse would look bad)
Most Classic, but will get dirty instantly: White Cotton wraps/Black San Marco saddle
If you go with a brown leather saddle: Shellacked Brown cork tape/Brown leather saddle
Hardest to set up but will look great: Shellacked Harlequin White/Orange or Tan/Orange cotton tape/Black Saddle
