Parity Penpalindromes by Cygne

Rules

Normal Sudoku rules apply.
Digits along a red and gray Parity Palindrome line read the same forward and backward, and alternate between odd and even.
Any set of three adjacent digits along a peach Entropy line must contain one small number (1, 2, 3), one medium number (4, 5, 6), and one large number (7, 8, 9).
Digits separated by a V add up to 5, and digits separated by an X add up to 10.

Nice use of colours for parity and letters for the palindrome’s made this an enjoyable solve. Thank you.

A very good puzzle. It should always be about the puzzle, and not the inaccuracies of links and codes. These test character.
