Final answer:
Natural colors from plants, such as henna, are known as organic colors and can be used for semi-permanent hair coloring or temporary body art.
Step-by-step explanation:
Natural colors such as henna, obtained from the leaves or bark of plants, are used for various purposes including hair coloring and body art. Henna, for instance, leaves a red or orange stain on the skin and is popular in many cultures for special occasions. These natural dyes can be used for temporary body art or semi-permanent hair coloring. Since they are derived from natural sources, they are often referred to as organic colors.
When it comes to hair dye specifically, these natural colors do not typically alter the structure of the hair permanently. They may fade after several washes and do not have the same lasting power as synthetic hair dyes classified as "permanent". Therefore, the correct answer to the question is (d) Organic colors, as these natural dyes are not temporary, semi-permanent, or permanent in the same way that synthetic dyes are classified.
