Colors Have Been Twinned

Title: Colors Have Been Twinned

Rating: 4/5

Please pardon the Pocahontas pun.  The puzzle above is not an alternate puzzle.  However, the cells at the following locations don't just abut--they intersect: (2,2), (2,5), (2,8), (5,2), (5,8), (8,2), (8,5), (8,8).  The colors in these cells are the average of the colors of the regions intersecting there.  For example, cell (5,8)--row 5, column 8--is contained in both the horizontal green region and the vertical blue region.


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.
