What is meant, speaking about "copper" hair color? What shades at the same time are meant? Copper is one of metals of which are characteristic saturated color tone. It is very difficult to confuse copper with iron or gold. Color of this metal is defined by features of its internal building.
Properties and color of copper
Copper represents very plastic metal. It differs from some other substances high electro- and heat conductivity. On these indicators metal ranks second, leaving on the first silver. Copper is considered diamagnetic. Other useful properties of copper: the high density, small specific resistance, an opportunity to add to this metal gloss.
On air this metal becomes covered almost at once by the oxidic film giving to material rich yellowish-red color. On a gleam the thin film seems greenish-blue.
Copper (along with gold, caesium and osmium) is one of metals which have the characteristic coloring different from the silvery or gray shades peculiar to other metals.
Scientists explain color of copper with characteristics of electronic transitions between atomic orbitals. The difference between them will be coordinated with the wavelength of orange light. The similar mechanism is responsible also for characteristic color of gold.
Copper alloys with zinc (brass), with tin (bronze), with nickel (cupronickel) and some other metals are known. Alloys of copper have the colors a little similar to shades of base metal. These derivative metals very peculiar look therefore they are often applied in the decorative purposes. Simplicity of processing is characteristic of bronze. And brass is resistant to impact of corrosion.
Copper: features of color schemes
If it is attentive and with addiction to consider a break of a copper core, then it is possible to see that it has some pinkish shade. Such type of a surface of metal is one of copper advantages doing it attractive to various industries. In particular, copper is widely used in construction (for example, as roofing material).
The richness of color and a wide variety of shades allows to receive products of desirable color. There was a time when roofed this classical yellowish-red metal. Further in copper there were chemical processes, it interacted with Wednesday. As a result the roof became the patina covered with a layer and accepted a malachite-green shade. Copper roofs with a layer of patina can serve decades.
Rather interesting color schemes give sulfate and oxide of copper. Crystals of oxide of copper have the expressed black color. This property of substance is used for giving to glass and paints and varnishes of the most various shades (including green and blue). Blue-turquoise color is characteristic of sulfate of copper.
