Colorplex Cool Bases

Cool Hair Color Bases 4F – 5F – 6F – 7F – 8F – 9F – 10F – 1.1 Blue-Black shade – base shades with bluish-grey reflection to neutralize yellow or golden undertones.

Not recommended for application on hair color levels 7, 8, 9, or 10 with 50% of gray hair, as its bluish-grey reflection helps enhance gray hair, adding more shine and making it more visible.

Recommended to apply on dark hair color levels or dark tones to create naturally looking hair roots preventing yellowish undertones from appearing.
