Perylene Maroon has a pigment number of PR179. Others in this range include Rowney Perylene Red.
Most though are Perylene Maroon. Daniel Smith Perylene Maroon is a dark, evocative pigment, slightly darker and much less saturated than the Winsor & Newton, which gives it a distinct brownish cast that is excellent for botanical illustrations. The Winsor & Newton is a duller, dark middle red, similar to perylene scarlet (PR149. I would recommend a Perylene Maroon as this is one I use often in mixes as a warm red. Hope the advice helps.
