Normal sudoku rules apply.
Shade cells using two colours such that each colour forms an orthogonally connected region, and no 2x2 area is a single colour.
A digit in a cell with arrows must match the total count of cells of the opposite colour in all given directions. For example, a 7 in a cell with arrows pointing east and south might be counting 4 cells to the south and 3 to the east. Every arrow points to at least one cell of the opposite colour.
Have fun, leave a comment if you enjoy the puzzle!
Lösungscode: Row 5

Made it on second attempt!
(Probably because I cannot count and forgot that 3+1=4)
Very nice puzzle, with very nice flow

I messed it up on the first try. But after 40 minutes on the second try I finally figured out what I should have seen a lot sooner.
Very glad I had not seen that it changed from 3 to 4 stars.
Often I will not try a 4 star. But this one was fun.

There we go! Lots of fun, and not so hard that I was burned out at the end.

A very fun YY puzzle. I felt like there was some kind of tension on the left and right edges of the grid. Spicy...

And I broke it anyway. Will have to try again later, got a lunch meeting.

Is it counting cells of the opposite color that are "seen"? or literally all cells of the opposite color in that direction regardless of any toggling?

Yes, I see that - that's the sentence for which I need clarification, not repetition.
** My hand was forced at one point, so it is every single cell of the opposite color, and its own color does not "block the view".
