Rules
Normal sudoku rules apply.
Digits along red parity lines must alternate between odd and even.
Any three adjacent digits along a teal modular line have different residues modulo 3 (i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}).
Digits separated by an X sum to 10.
Digits in grey cells must be higher than all orthogonally adjacent cells.
Digits cannot repeat within the same constraint type.
Solution code: Column 6
