Rorschach II

Title: Rorschach II

Rating: 5/5

One of the hardest puzzles I've ever created, and a sequel to the infamous original, and the final sum puzzle I've created.  Note also the overlapping regions for an extra challenge (see the final rule).  Enjoy (?).

The official rules:

• The digits 1 through 9 appear in each row and each column exactly once.
• Digits in each shaded region must add to the indicated sum.   
• Squares with multiple colors contain a number that’s used in the sum for adjacent regions of each of those colors.
• Remember: numbers can repeat within a shaded region if that doesn't violate the first rule.
• Cells at the following (row, column) positions belong to the regions that go horizontally and vertically through that cell: (2,3), (2,7),(3,2),(3,8),(7,2),(7,8),(8,3),(8,7).
