Final answer:
Permanent hair colors are capable of both lightening the natural pigment and depositing artificial pigment in a single process.
Step-by-step explanation:
The type of hair colors capable of lightening natural pigment and depositing artificial pigment in a single process are permanent colors. Permanent hair coloring involves a chemical change in the hair's structure, where the natural color is removed and synthetic color is inserted in its place. This process typically involves three components: an aromatic amine or diamine, a coupler, and an oxidant. The aromatic amine undergoes an oxidation reaction to create a larger dye molecule that is locked inside the hair, resulting in a permanent change of hair color.
