After my extremely long modular line puzzle, Modulo Oblongata, I wanted to try to make an extremely long palindrome line. Hope you enjoy!
Solution code: Column 9, top to bottom

Letters, then colours, then candidates, then constraints :D
Super fun!

that was fun. i prefer letters when so much coloring is needed

Very easy if you know how to handle "long palindrome" puzzles. I use colors because filling the box is easier to read than staring at little letters.

Going from no digits placed to finished in 30 seconds was very satisfying. Ty for the puzzle. :D

I just read in the comments that someone uses letters instead of coloring for candidate marking. My mind is blown, letters are for disambiguating colors or for candidates in chaos construction when you need colors for regions. This is the only way

Funny „Madam, I’m Adam“-construction. Thank you very much for creating and sharing.

Beautiful coloring exercise!

That was a fun puzzle. I like puzzles that I can solve completely with letters before I even begin to fill in the numbers.
