This term is primarily used in technical, artistic, and scientific contexts to describe a process of elimination. In sculpture and manufacturing, it refers to the physical removal of material, contrasting with additive processes like 3D printing or clay modeling where material is built up.
In the context of optics and printing, it describes a specific color theory where pigments absorb certain wavelengths of light. This is the opposite of additive color mixing, such as that used in digital screens, where light is added together to create white.
