Rules
Normal sudoku rules apply.
Digits along red parity lines must alternate between odd and even.
Along pink lines, digits form a consecutive sequence in any order.
Along orange lines, adjacent digits differ by at least 4.
Any three adjacent digits along teal modular lines have different residues modulo 3 (i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}).
A digit in a blue square indicates the number of even digits which appear along the attached line.
Solution code: Column 9
