And here is a hint to get you started, it is possible to find (or limit to a few candidates) the values for the greyed cells below:

4 | |||||

1 | |||||

3 | |||||

2 | |||||

When this is done, the value for blue and pink pieces can be found with a bit of logic. At this point, solving the puzzle should not be too hard :)

Great puzzle!

Here was my walkthrough for the beginning:

RxCy means Row x Column y

r is red sum, b is blue sum

| means "or"

Rows 1 and 2 contain 2 red and blue (r and b) sections.

42 (R1+R2)=2r+2b

21=r+b

R6C123=21-r=b

R6C1=R5C3=2

R3C4 = 2r+4b-63 = 42+2b-63 = 2b-21

b is 11|12|13

R3C4 is 1|3|5

R3C1-4 is {1235|1236|1345}

r is 10|9|8

r can't be 8 because that would remove all possibilities for R4C123

I wish I hadn't accidentally seen the hint. I would suggest making hints hidden in some way.
