All denominations (20, 50, 100, 200, 500, and 1,000 pesos) are being redesigned, but their colors will remain the same. Guinigundo said new personalities will be added to some of the notes, and existing portraits will be updated, while the backgrounds and vignettes will be changed to include the country’s famous tourist spots. New and old notes will circulate in parallel for up to three years.
