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 ossicles (also called auditory ossicles) are three bones in either middle ear that are among the smallest bones in the human body.They serve to transmit sounds from the air to the fluid-filled labyrinth (cochlea).he structure is known as the middle ear, and is made up of the stapes, incus, malleus, and tympanic membrane. These correspond to the columella, quadrate, articular, and angular structures in the amphibian, bird or reptile jaw.
