Hendiadyoin Sudoku

(Published on 17. October 2021, 06:00 by ICHTUES)

- Normal Sudoku rules apply; twice (digit and colour). So each row, column and 3x3 box contain the digits 1 to 9 exactly once. Additionally each row, column and 3x3 box contain 9 different colours exactly once.
- Each of those 9 sets of colour contains the digits (1-9).

Wow, what a wonderful and fun puzzle! It took me way longer than it should be to notice the missing pencil mark, almost challenged my scanning to the limit. Very rewarding at the end :)

Loved this puzzle! Very narrow solve path but if you can find the steps then they are not too difficult to understand. Great fun!

I added the given colour in r7c9, because the puzzle had 2 solutions until now. Thanks very much to Vebby, who pointed that out and had the idea of giving exactly that last given.
