Rules
Normal sudoku rules apply.
Box borders divide the blue line into segments with the same sum.
Along the orange line, adjacent digits differ by at least 4.
Along the green line, adjacent digits differ by at least 5.
Along the pink line, digits form a consecutive sequence in any order.
Along the red parity line, digits must alternate between odd and even.
The white dot joins digits whose difference is 4.
Additionally, the digit 4 is subject to the anti-knight rule, meaning that it cannot see another 4 a knight's move away.
Solution code: Row 4

Very nice puzzle, and nice quote in the solution! Incidentally, your name sounds like it could be the secret identity of a F4 member.

I got stuck a long time with multiple solutions before understanding that the blue line in the middle box is made of only one "segment" : the 5 five cells on the line add up !

ND: Sorry about that, glad you figured it out.
