Scientists refer to color in terms of wavelength, a characteristic of electromagnetic radiation, but there is no universal match of specific wavelength values to specific color names.
Sky surveys and mappings of the various wavelength bands of electromagnetic radiation (in particular 21 - cm emission) have yielded much information on the content and character of the universe's structure.
Upon exposing a metallic surface to electromagnetic radiation that is above the threshold frequency or threshold wavelength (which is specific to the type of surface and material), the photons are absorbed and current is produced.
