Heat from the sun, in the form of shorter-wavelength radiation, passes through the glazing largely unimpeded. When this radiation strikes the dark colored surface of the thermal mass facing the sun, the energy is absorbed and then re-emitted in the form of longer-wavelength radiation that cannot pass through the glazing as readily.
When light strikes Vantablack, instead of bouncing off, it becomes trapped and continually deflected amongst the tubes, absorbed, and eventually dissipated as heat. [24] CVD Vantablack was an improvement over similar substances developed at the time. Vantablack absorbs up to 99.965% of visible light and can be created at 400 °C (752 °F).
Chameleons - Colour change signals a chameleon's physiological condition and intentions to other chameleons. [3] [4] Because chameleons are ectothermic, they change color also to regulate their body temperatures, either to a darker color to absorb light and heat to raise their temperature, or to a lighter color to reflect light and heat, thereby either stabilizing or lowering their body ...
An urban heat island occurs where the combination of heat-absorbing infrastructure such as dark asphalt parking lots and road pavement and expanses of black rooftops, coupled with sparse vegetation, raises air temperature by 1 to 3 °C (1.8 to 5.4 °F) higher than the temperature in the surrounding countryside.

The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [1] [2] Color temperature has applications in lighting, [3] photography, [4] videography, [5] publishing, [6] manufacturing, [7] astrophysics, [8] and other fields.
Here are designers favorite dark gray paint colors for both interiors and exteriors to give your home a look that is warm and inviting, and not at all gloomy.
If the reflectance spectrum of a color is 1 (100%) for all the wavelengths between A and B, and 0 for all the wavelengths of the other half of the color space, then that color is a maximum chroma color, semichrome, or full color (this is the explanation to why they were called semichromes). Thus, maximum chroma colors are a type of optimal color.
