Rules:
Normal sudoku rules apply.
Anti-knight: Cells that are a knight's move apart (in chess) cannot contain the same digit.
Anti-diagonal: Each main diagonal contains exactly 3 unique digits.
Palindrome: The sequence of digits along the thick gray line reads the same in both directions.
Kropki: A white dot joins two consecutive digits and a black dot joins digits in a 1:2 ratio. Not all dots are not necessarily given.

Very nice colouring puzzle, definitely feels like the harder end of 2 stars/easier end of 3 stars to me

More of a 3 star than a 2 star to me. Very fun!
