Logic Masters Deutschland e.V.

Recently I've been hooked on making Sudoku puzzles inspired by the mystery stories I read. The idea behind this one is simply that I noticed there are too many red-green colour-blind suspects in mystery stories. The difficulty is probably around 3.5*. Many thanks to cyddrdrd for testing!

Rules:

• Normal Sudoku rules apply: Place the digits 1–9 once each in every row, column, and 3x3 box.
• Grey lines:
  • A grey line is either a Parity line or a German Whisper line, to be deduced by the solver.
  • Digits along a grey line CANNOT repeat.
  • Parity lines: Adjacent digits along a red line must alternate between odd and even.
  • German Whispers: Adjacent digits along a green line must differ by at least 5.
