Stretch marks

Just a little bit of renban fun.
- Normal sudoku rules apply: each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Renban: each pink line contains a set of consecutive, non-repeating digits, in any order.
- Palindromes: both grey two-cell paths are palindromes. The digits in both cells of a palindrome are equal.

Enjoy!
Solution code: Row 1 and column 8. I.e. the 9 digits in row 1 from left to right, followed by the 9 digits in column 8 from top to bottom, for example: 123456789123456789

Stretched the old grey matter nicely, thanks, after quite a quick start.

I found the ending to be quite tricky to spot, but very satisfying. Beautiful puzzle!

Well, the first 5 numbers were easy at least. As my first renban puzzle I feel like I fell in at the deep end, but had so much fun unteasing the logic.

Another puzzle where I wish I had, like, 15 colors to use.
