Seeing red, seeing double

Somedoku: In each cell, place a digit from 1-6. In row N, there must be exactly N distinct digits. Also in column N, there must be exactly N distinct digits.
Yin Yang: colour each cell one of two colours, such that the grid is divided into two orthogonally connected regions, one of each colour. No 2 x 2 square may consist of cells of one colour only. Doublers: all shaded cells have a value double that of their digit.
Balancer lines: along each red line, the sum of the values of the cells of one colour must equal the sum of the values of the cells of the other colour.
A hint may be useful, which is a third secret about Yin Yang puzzles in general

Excellent puzzle! My favorite flavors of logic are all packed neatly into a small 6x6 box :)

Beautiful puzzle! Very satisfying how the logic required to open the next part kept shifting. Thank you!
