Foggy Odd Even-ing
Rules:
⚪ Normal Sudoku rules apply. Placing correct digits reveals the fog in the surrounding cells. Guessing is not needed.
⚪ Kropki pairs: White dots indicate consecutive digits.
Black dots indicate digits with a ratio of 1:2.
Not all dots are necessarily given.
⚪ Indexing: Red cells are column indexing, e. g. a 7 in R9C2 puts a 2 in R9C7.
Green cells are row indexing, e. g. a 7 in R9C2 puts a 9 in R7C2.
⚪ Color-Cages: Digits in cages do not repeat.
If a cage total is even, all cells of that cage have to be shaded red, otherwise green.

olima: you have to find out the color as part of the solving…
