In honor of summer, hope you find this puzzle refreshing! Be sure to pay attention to the specifics of the negative constraint. Welcome any comments and/or feedback :)

Rules:

1. Kropki: cells separated by a white dot have a difference of 1 and cells separated by a black dot have a ratio of 2:1

2. Negative constraint: All possible dots within each caged/colored ring are given. (i.e. Only orthogonally adjacent cells in the same cage/color have a negative constraint applied to them)

3. Standard Sudoku rules apply
