Metallic color

This cannot be reproduced by a simple solid color, 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 or fluorescent colors on a computer without resorting to rendering software which simulates the action of light on a shiny surface.

However, the metallic finish of such paints was added using fine aluminum powder and pigment rather than actual gold.

In some instances, it has been noted, "beetles with bright metallic colors are made up into tie pins and cuff links".

Such colors "are made from a combination of different pigments and aluminum flakes that have different weights and particle sizes".
