Monday Mutant 9: Polyominous (odd/even)

Monday Mutants is a series in which I will attempt to experiment with "mutant" puzzles. These could be existing puzzle types with an unusual change in the rules, hybrids combining elements from multiple puzzle types, or puzzle types neither invented nor popularized by Nikoli.
In this Polyominous puzzle, when the entire puzzle is filled with numbers, the darker shaded cells may only contain even numbers, and the lighter shaded cells may only contain odd numbers. The rules are otherwise unchanged.
