The sum of the blue (15 cell) area is as large as it can be, with the sum given in the 2 cell blue area.
Standard Sudoku rules apply.
Little Killer diagonals sum to the given value and may include repeated digits.

Zur Klarstellung: Die rote Summe muss so klein wie möglich sein. Unter allen Lösungen mit dieser minimalen roten Summe ist dann die gesucht, bei der die blaue Summe am größten ist.
-- That is correct Stefan. Glad you managed to solve it!

Add tags, add text about solving min before max.

@steelwool: It seems like there was a written mistake in the update, which could caused the un-labeling.
I'm sorry for the inconvenience :)

Since this is a Sudoku puzzle, could you please add the sudoku tag?
-- Hi, the setup seems to have changed. It asked me if I was entering a sudoku and I said yes. There is no symbol for sudoku to select any longer, so I am surprised it didn't get added after the question. Added as a bespoke tag
