Standard irregular Sudoku rules - each row, column, and 9-cell region must contain the digits 1-9. Diagonal constraint applies - each main diagonal of the puzzle must include the digits 1-9. Standard thermometer rules - digits on thermometers must increase from the bulb to the tip.
The long-awaited (?) sequel to the Zeroth Law of Chromodynamics. Penpa link included for solvers who would like to use letters as placeholders for unknown digits.
Puzzle is available at F-puzzles or Penpa.
As always, any feedback you have is highly appreciated!
Solution code: Row 2 and column 9, no spaces

Holy moly. This is a new hardest for me. Getting every pencilmark was very very hard. The ending made it all worth it tho. Lovely puzzle. Thank you for making it!

I found this more difficult to unwind than the first puzzle, but it was just as fun to solve! Thanks for the Penpa link, it really helped me, being colorblind (I prefer the f-puzzles interface, but Penpa is hard to beat for features).
