Ametallic color is a color that appears to be that of a polishedmetal. The visual sensation usually associated with metals is its metallicshine. This cannot be reproduced by a simple solidcolor, because the shiny effect is due to the material's brightness varying with the surface angle to the light source. In addition, there is no mechanism for showing metallic orfluorescent colors on acomputer without resorting to rendering software which simulates the action of light on a shiny surface. Consequently inart and inheraldry one would normally use a metallic paint that glitters like a real metal.
Especially in sacral art in Christian churches, real gold (asgold leaf) was used for rendering gold in paintings, e.g. for thehalo ofsaints. Gold can also be woven into sheets of silk to give an East Asian traditional look. More recent art styles, for exampleArt Nouveau, also used a metallic, shining gold. However, the metallic finish of such paints was added using finealuminum powder and pigment rather than actual gold.
The use of metallic colors is not limited to those colors that approximate the appearance of actual metals. In some instances, it has been noted, "beetles with bright metallic colors are made up into tie pins and cuff links".[1] One popular modern use of metallic colors is forautomobiles, which usemetallic paint to achieve a particular shine. Such colors "are made from a combination of different pigments and aluminum flakes that have different weights and particle sizes".[2]Crayon-makerCrayola has manufactured several lines of "metallic" products, including "Metallic FX" crayons,[3] and "Metallic Colors" colored pencils, which have flecks of sparkles to achieve the metallic effect.
