ARTIST QUALITY PAINTS
Every pigment has a unique Colour Index Name, consisting of two letters and some numbers. It’s not a complex code, the two letters stand for the colour family e.g. PR - Red, PY = Yellow, PB = Blue, PG = Green. This, plus the number identifies a specific pigment. For example, PR108 is Cadmium Seleno-Sulfide (common name Cadmium Red), PY3 is Arylide Yellow (common name Lemon Yellow).
