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 Middle Ear is the portion of the ear internal to the eardrum, and external to the oval window of the inner ear. Also mammalian middle ear contains three ossicles, which transfers the vibrations of the eardrum into waves in the fluid and membranes of the inner ear.The hollow space of the middle ear has also been called the tympanic cavity, or cavum tympani.ain article: Ossicles.
