When exposed to oxygen, it turns blue, deepening in intensity with increased ingress. The rate of the color change is proportional to the rate of oxygen entering the package and can be correlated to conventional oxygen transmission rates.

The Physical Properties of Oxygen are as follows:

• Color : Colorless.
• Phase : Gas.
• Odor : Oxygen is an odorless gas.
• Taste : A tasteless gas.
• Conductivity : A poor conductor of heat and electricity.
• Solubility : Slightly soluble in water, alcohol and some other common liquids.
• Density : It is denser than air.

Oxygen is a highly reactive element, highly paramagnetic, and is easily capable of combining with other elements. One of oxygen’s most important chemical properties is that it supports combustion. Oxygen also combines with elements at room temperature, for example, the formation of rust.

Under standard conditions oxygen forms a gas that is composed of molecules consisting of two oxygen atoms (O2). This is called a diatomic gas. In this form oxygen is a colorless, odorless, tasteless gas.

This absorption requires light from the red region of the spectrum (~630 nm). If red light is absorbed , then blue light is transmitted or reflected and this gives rise to the blue color associated with liquid oxygen.

Oxygen is a nonmetal. It has low thermal and electrical conductivity, but high electronegativity and ionization energy. The solid form is brittle rather than malleable or ductile.

It’s Cherenkov Radiation. Caused by particles traveling faster than light through a medium, Cherenkov Radiation is what gives nuclear reactors their eerie blue glow. In the miniseries “Chernobyl” when the reactor first explodes, there’s an eerie blue light emanating from it.

Did you know? These are the rarest colours in the world

1. Lapis Lazuli. Lapus Lazuli is a blue mineral so rare that in the Middle Ages and the Renaissance it was actually more valuable than gold.
2. Quercitron.
3. Cochineal.
4. Dragon’s Blood.
5. Mummy Brown.
6. Brazilwood.
7. Cadmium Yellow.

Green eyes are the rarest color. Brown eyes are the most common. People can also have blue eyes, (Learn More) gray eyes, (Learn More) or hazel eyes.

The Controversial Color That’ll Make Any Outfit Look Expensive. As a rule of thumb, if you’re on a tight budget and you want your outfit to look polished and conceivably expensive, the easiest route to go is wearing neutrals. Black, brown, white, beige—you get the point.

Based on this, vehicles that are white or black are likely to cost more to insure, since they are more in demand colors. The color of your car can indirectly affect insurance rates in other ways too.

Tyrian purple

The middle class could usually afford to dye their wool colours like blue and green. The wealthy could afford to add elaborate designs to their clothing as well as dying it red and black, expensive colours for the time.

The commoner version would be orange and yellow, most likely. Silk. This stuff was high class and it was illegal for commoners to even wear it. Undyed silk was very rare.

White for Purity, Gold for Wealth; Purple, Violet, and Blue for Royalty and Piety.
