Theme: Fade to Gray
Author/Opus: This is the 187th puzzle from clover!, part of the Genuinely Approachable Sudoku (GAS) team.
Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). If a circle is given between two adjacent cells, then it means that either (A) the two numbers in those cells must differ by 1, or (B) the two numbers must have a ratio of 2. Pairs of cells without circles can have any relationship.
