The process in this case is âsubtractive,â since the pigments subtract or absorb some of the wavelengths of light. With transparent dyes, like our Fiber Reactive Dyes that we use for Tie-Dye, Cyan (blue-green), Magenta (red-violet), and Yellow and are called subtractive primaries, or primary colors.he process in this case is âsubtractive,â since the pigments subtract or absorb some of the wavelengths of light.

The eardrum (tympanic membrane) is a thin, oval layer of tissue deep in the ear canal. It helps protect the delicate middle and inner ear from the outside. It is called an eardrum because it looks and acts like a drum. The eardrum receives vibrations from the outer ear and transmits them to the small hearing bones (ossicles), of the middle ear. Because it is so thin, the eardrum can be ruptured or punctured. The hole exposes the middle and inner ear to damage or infection. Picture of the inner and outer structures of the ear.
