Editing Metamerism (color) (section)

=== Textile industry ===
Color matching in the textile [[dyeing]] industry is essential. In this branch, three types of metamerism are commonly encountered: illuminant metamerism, observer metamerism and field-size metamerism.{{cn|date=February 2024}} Due to the wide range of different illuminants in modern life, textile color matching is difficult to ensure. Metamerism on large textile items can be resolved by using different light sources when comparing colors. However, metamerism in smaller items such as textile fibers, is more difficult to be solved. This difficulty arises due to the necessity of a microscope, which has one single illumination source, to observe these small fibers. Therefore, metameric fibres cannot be distinguished neither macroscopically nor microscopically. A method which can solve metamerism in fibres combines [[microscopy]] and [[spectroscopy]], and is called microspectroscopy.<ref>{{cite book |last1=Houck |first1=Max |title=Identification of Textile Fibers |date=2009 |publisher=Elsevier}}</ref>
