In a sense, an iridescent finish is colorless, but the high sheen and translucent effect gives off a light refraction that appears to have various rainbow-like hues and colors in it. An iridescent finish is glossy, shiny and slick.

Peacock feathers give the visual effect of iridescent lighting.

Cultured pearls, ivory, butterfly wings and other natural items are examples of what iridescent finishes should look like on different manufactured products, from paints and furnishings to buttons and jewels.


The polished granite used in architecture is iridescent in color.

The application of metallic and iridescent finishes in an architectural process requires expert skill, the right kinds of materials and equipment, and a good air supply. Metallic and iridescent coatings are translucent and easily penetrated by ultraviolet light. Spray paints and polyurethane semi-gloss or satin coatings such as those used for sculptures, signs and watercraft are smooth finishes.


Thousands of iridescent lights finish chandeliers and other fixtures.

The most common type of iridescent finish is on the many different types of available lighting, including outdoor ceiling lights, Peruvian, Quoizel and Tiffany lamps, and indoor recessed lighting. Iridescent light bulbs such as flame-shaped halogens and novelty Christmas lights come in many different styles and finishes.


Eye, cheek and face makeup with a shiny finish contains iridescent minerals

Iridescent powders are mixtures of Mica -- a light, soft heat-resistant mineral -- and color pigments that give skin and other facial and body features a glossy sheen, glitter or glow. These powdery or creamy cosmetic minerals are used alone or mixed with foundations, moisturizers or other cosmetics.

Fashion and Jewelry

Seashell interiors give off a polished iridescent lighting effect.

A shiny iridescent finish seems to recede optically. These finishes are best for highlights and accents. The iridescent "rainbow" finish is also known as aurora borealis in that it can totally change the original color of a bead in different light, or when turned in different directions under light. Iridescent bead colors and stylized or plain buttons come in matte or metallic finishes. On fabrics, organza and taffeta can both have iridescent finishes that make cloth appear to glisten under the right lighting. Sequins also give off an iridescent finish.

Other Iridescent Finishes

Cultured pearl on black background defines iridescent finish.

Dishes, glass, kitchen appliances, airbrush paints, wall finishes and sometimes even meats such as roast beef can have an iridescent color or streak. Some fishing rods and lures are made with a polychromatic or prismatic iridescent effect to attract fish with the reflection in the water.

Producing Iridescent Coatings: Mica Pigment

Mica is a shiny silicate mineral found in granite or crystal.

You can produce an iridescent reflecting surface by using mica powder with a metal oxide mixture, such as titanium oxide. Titanium oxide is a white powder used as a pigment because when it's mixed with other powders or minerals, it changes the color of the mineral depending on how much titanium oxide is used. The chemical reaction between the elements make the color, or pigment, of the base mineral.
