Buying it right
Phthalo green blue shade for a cooler green.
Phthalo green comes in two directions. The phthalo green blue shade, Pigment Green 7, gives the cool green that ink and paint plants use as a mixing base.
Hongda carries it as HD-G for inks, paints and general use and HD-8730K for plastics at 280°C. Each grade lists the multinational standard it replaces.
If your formula calls for the yellower direction, Pigment Green 36 sits in the same range. The pigment team sends both for a side by side drawdown.
