Two Colors, One Bishop

Rules:

Normal Sudoku: Place the digits 1–9 so that each row, column, and 3×3 box contains each digit exactly once.

Killer Cages: Digits in a cage may not repeat and sum to the total given.

Renban Lines: Digits along a purple line form a set of consecutive digits in any order.

Bishop Move: The grid is pre-shaded like a checkerboard in yellow and blue. Exactly one of the two colors acts as a no-bishop-move color (to be deduced by the solver), meaning digits cannot repeat along any diagonal within that color. The other color has no diagonal restrictions.
