Broken Promise

Normal sudoku rules apply. Put the Digits 1 - 9 in every row, column and 3x3 box.
Black Kropki: Digits separated by a black dot indicate one digit is double the other. Not all possible dots are shown.
Killer Cages: Digits in killer cages sum to the number in the top-left corner. Digits may not repeat within a cage.
Little Killers: A clue outside the grid gives the sum of the digits along the indicated diagonal.
German Whisper: Digits on a green line must differ by at least 5 from adjacent digits.
Renban: Digits on a pink line must be a string of consecutive digits. These digits can be placed in ANY order.
Entropic: Any set of three consecutive cells along a peach entropic line contains one low digit (1–3), one medium digit (4–6), and one high digit (7–9).
Parity: Adjacent digits along the red parity line must alternate between odd and even.
I'm sorry... It happened again! I forgot to colour the lines. There are one of each so surely you can figure it out right? Like I said before, and I really mean it this time, it won't happen again!
Those are the rules! Good luck!

Such a lovely puzzle, I hope you keep forgetting your colors! I only wish the lines were a lighter grey next time, the pencil marks can be hard to read

I enjoyed this puzzle a lot, but you need to be more careful about your colors. This is twice. Careless.

Much harder than 2*, I'd say 4* at least. Some tricky deductions, even after you've identified the line types.

Loved it! I found it more of a 3-star difficulty (just timewise for the deductions), but it was super enjoyable. Thank you for making this!

Don't worry, we're here to help you find the colors.
Very fun puzzle and the disambiguation wasn't too hard.
PS. I agree that the grey lines could be thinner or lighter to help with visibility.

Thank you very much for creating and sharing another lovely disambiguation puzzle. (No need to explain White Kropki here …)

A touch harder than the last one maybe, really enjoying these.
Can I also second the suggestion of using a lighter grey.

Maybe consider using a lighter shade of grey, since some of the pencilmarks are hard to read. Other than that, very fun puzzle with good flow, thank you for setting!
