Odd Mutant

Normal Sudoku rules apply. Numbers in gray circles are odd. Numbers in cages sum to the number in the top left corner of the cage. Numbers cannot repeat in cages. Numbers in GREEN cells are the SUM of two of the orthogonally adjacent odd numbers. Numbers in RED cells are the DIFFERENCE of two of the orthogonally adjacent odd numbers. The number in the BLUE cell has BOTH green and red properties. All possible green, red and blue cells are shown.
