Neutral Tint is a transparent gray (black in masstone) that is specifically designed to be neutral: not warm, not cool, not leaning toward any other color.
Typically, Neutral Tint is made from a mix of three pigments: PBk6 (Lamp Black), PV19 (any number of quinacridone magenta/pink/rose/purple/crimson shades), and PB15 (Phthalo Blue of some sort).
Manganese Blue Hue, made from the same pigment as the Phthalo Blues but designed to mimic the original Manganese Blue, which is a non-staining, liftable, and granulating light blue.
Phthalocyanine blue (PB15) is an incredibly intense, staining, transparent, non-granulating, lightfast pigment that comes in two versions:
(I’ll call them GS and RS in this post.)
What’s the difference, and which should you choose?
