Scientists of the International Tomography Center (ITC), RAS, have developed a unique complex substance that unlike most previously known matters, does not turn pale in the cold, but enhances its color instead.
According to Victor Ovcharenko, the head of the ITC, the find is useful for operation in the Arctic and will at least make life easier for school pupils in the polar regions.
 "Generally, the higher the temperature, the brighter the colours are. It is clear that colours are brighter in summer than in winte. The lower the temperature, the lower the thermal excitation is, and vice versa. If we, for example, make metal burning hot, it will be red brightness, glowing heat, and so on, and when cooled, everything becomes faded, losing its colour. But we have got an amazing compound that deepens it`s colour when cooling down"- the scientist pointed out.
The new compound, its composition still undisclosed, opens up wide opportunities for using in the North, for example, as an indicator of dangerously low temperature.
"Imagine that children go to school, and  right at the entrance there is a large panel, which has all lit up in red colour or displays a bright red announcement that the school is not working due to extreme cold," - he said.
Mr. Ovcharenko added that such a device does not require a source of electric supply.
