Seeing Colors
Rules:
- Normal sudoku rules apply.
- Yin-Yang: Color the grid using two colors such that all cells of the same color are orthogonally connected and no 2x2 area is fully one color.
- Clues outside the grid indicate the total number of cells in the respective row or column that are one of the two colors. Different outside clues may be referencing different colors.
- Digits in circles indicate the total number of cells of the same color seen orthogonally from that cell, including itself. Cells of the other color block vision. *All circles are given!*
- Renban: Digits on a pink line form a set of consecutive, non-repeating digits in any order.
Enjoy!

Rsolving the yin-yang was very cool. A bit tricky towards the end. Thanks!
