Normal sudoku rules apply.
Form a one-cell-wide loop that moves through the grid orthogonally. The loop does not touch itself, not even diagonally. A loop cell is an odd digit if the loop moves straight through it, and is an even digit if the loop turns at its location. Digits along the loop are ascending or descending, with 1 and 9 reversing the direction.
Cells separated by a black or white dot are either both loop cells, or neither are loop cells. Digits separated by a black dot have a 1:2 ratio. Digits separated by a white dot are consecutive.
Two cells connected by a green line have a difference of at least 5.
Two cells connected by a red line contain opposite parities.
A pink line contains a consecutive set of digits in any order, without repeats.
All lines consist of exactly one loop cell.

Really nice puzzle. Thank you. I got stuck near the end, but then remembered the ascending/ descending rule.
