Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
In tropical Australia, zinc-galvanized (silvery) sheeting (usually corrugated) do not reflect heat as well as the truly "cool" color of white, especially as metallic surfaces fail to emit infrared back to the sky. [67] European fashion trends are now using darker-colored aluminium roofing, to pursue consumer fashions.
Correlated color temperature (CCT, T cp) refers to the temperature of a Planckian radiator whose perceived color most closely resembles that of a given stimulus at the same brightness and under specified viewing conditions."

The colors are intense and seem to be caused by Cu(I)–Hg(II) charge-transfer complexes. [7] Silver mercury iodide (Ag 2 [HgI 4]) is yellow at low temperatures and orange above 47–51 °C, with intermediate yellow-orange states. The colors are intense and seem to be caused by Ag(I)–Hg(II) charge-transfer complexes. [7]
Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact ...
LAS VEGAS (AP) — Scorching heat across the U.S. already has caused more than a dozen deaths in Texas alone and led to mounting misery for millions of people from the Pacific Northwest to the ...
