Wouldn't say it's as easy as the existing comments do. Completed it in the end though.

Great, still approachable puzzle that manages to save a lot of deductions around variants for the final phase! (I don‘t like the variants that give you some initial digits and then leave you with a ton of Sudoku.

Is the puzzle title some computer code for a colour? White maybe?
