  2. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    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.

  3. Correlated color temperature - Wikipedia

    en.wikipedia.org/wiki/Correlated_color_temperature

    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."

  4. Emissivity - Wikipedia

    en.wikipedia.org/wiki/Emissivity

    The planets are solar thermal collectors on a large scale. The temperature of a planet's surface is determined by the balance between the heat absorbed by the planet from sunlight, heat emitted from its core, and thermal radiation emitted back into space. Emissivity of a planet is determined by the nature of its surface and atmosphere. [11]

  5. List of thermal conductivities - Wikipedia

    en.wikipedia.org/wiki/List_of_thermal_conductivities

    In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature. [1] Thermal conductivity is often measured with laser flash analysis. Alternative measurements are also established.

  6. UV coloration in flowers - Wikipedia

    en.wikipedia.org/wiki/UV_coloration_in_flowers

    The visible color of the flower impacts the UV color. [9] Yellow flowers having the greatest measure of reflectance. [5] It is more typical to observe UV coloration in purple, red and yellow flowers while white and green ones are less likely. [2]

  7. Hue-heat hypothesis - Wikipedia

    Taj Mahal in warm light from a low elevation sun. Taj Mahal in the cold light from a high elevation sun. The hue-heat hypothesis is the hypothesis that an environment with warm colors (red, orange yellow hues) will feel warmer in terms of temperature and comfort, while an environment with cold colors (blue, green hues) will feel cooler.

  8. Temperature sensitive glass - Wikipedia

    en.wikipedia.org/wiki/Temperature_Sensitive_Glass

    Visual glass goes through a gradual progression while altering colors stages in different heat zones. [2] In order for specific light wavelengths to be reflected off of a temperature sensitive glass, it has to go through one of three main heat phases. In accelerated temperature zones, the crystals respond in the nematic phase.

  9. Thermochromic ink - Wikipedia

    en.wikipedia.org/wiki/Thermochromic_ink

    Thermochromic ink (also called thermochromatic ink) is a type of dye that changes color in response to a change in temperature. [1] [2] [3] It was first used in the 1970s in novelty toys like mood rings, but has found some practical uses in things such as thermometers, product packaging, and pens. [4]
