Puzzle: It's a killer

Rules:

Normal 9x9 Sudoku rules apply, place the digits 1-9 once each, in every row, column and 3x3 box.

Killer Cages: Every Killer cage has a different sum from 1 to 15. Digits cannot repeat in cages. (Cages are coloured to identify different size cages: Green - 1 cell, Amber - 2 cells, Red, 3 cells).

Kropki: Digits separated by a black dot are in a 2:1 ratio. Digits separated by a white dot are consecutive. Not all dots are given.
