Normal Sudoku rules apply.
Knight constraint applies, cells that are a chess knight's move apart must not contain the same digit.
Little Killer digit of 47 outside the cage is the sum of the digits along the diagonal. Numbers may repeat if allowed by other rules.
Black dots indicate a 2:1 ratio between the cells values. White dots indicate that the adjoining cells contain consecutive numbers. There is no negative constraint and not all dots are provided.
Inspired by Polycarp's puzzle Just Add Colour.

This was so fun to solve. my first attempt went wrong. So I came back and tried again from the start and found it not too tough. Just needs some knight logic

Spent 5.5 hours only to find that the killer clue didn't work with the logic I used. I don't know if I have the heart to try again

Oh wow, that's a really good puzzle! I'm always amazed by coloring puzzles, really liked this one! Just have the right amount of difficulty (for me, at least), loads of interesting logic, and a pleasing finish... thanks for that! :)

Nice one! I couldn't suppress a giggle at the last disambiguation. :-D
