Marine Blue has an iron oxide and ultramarine base. It has been blended to provide a pleasant balance of not predominantly blue nor overly black.
To increase the blue tones, add a dash of Sapphire Blue or should you want black tones, add Black Onyx. We would caution you never to use this on eyebrows and never on lips.
The pigment comes in a 1/2 oz. sealed bottle, packaged with a separate dispensing twist top cap.
