This black pigment greatly absorbs the reflection of blue light because of its special surface structure. Powder Black is hence a deep black when applied purely. PB shows comparably only little blueish discoloration even when it remains beneath the skin for a long time.
This black pigment can additionally be used to apply beautifully powdery eyeliners.
Powder Black is the only black pigment that can be used to tone down warm brown pigments (WB or DR). This combination can be used to apply rather dark brows. But, be careful – only add the colour pigment drop by drop.
