Describes the spectral energy distribution and thereby the colour quality of a light source. The temperature of a colour is given in Kelvin (K). It is important to choose the correct temperature so that a subject can be photographed in its true colours. The spectrum that can be seen by the human eye lies between approx. 2,790 K and 11,000 K.

A measure of the warmth or coolness of light sources and colours. Measured in degrees Kelvin. The human brain automatically compensates for different colour temperatures - a film or video camera cannot, and thus what we see as white may appear to have a blue or green tint when no colour correction is used for video. Daylight is approximately 5600K and Tungsten Halogen is approx. 3200K.

A description of the colour of the emissions from a light source in 'kelvins'. Lower values are redder, higher values bluer. The standard colour temperatures for a monitor is 6500æK despite the fact that when delivered they are generally in the 9300æK to 11000æK range. A light box or reflective viewing area should be standardised at 5000æK.

The measure of the colour of a light source by relating it to a theoretically perfect black body source of radiant energy, measured in degrees Kelvin (°K).

Measurement of the colour of light, often expressed in Kelvin. The human eye adjusts for colour temperature most of the time without our noticing it; on a camcorder the automatic white balance system performs the same adjustment.

Colour temperature in Kelvin (K) is a term to describe the colour appearance of a light source, related to the colour of a black body radiator. If the colour point for the source does not lie on the black body locus, its colour temperature is given by the temperature of the black body which it most closely matches, and is its correlated temperature. The measurement can also be described as the "warmth" or "coolness" of a light source. Generally, sources below 3200K are considered "warm;" while those above 4000K are considered "cool" sources.

The colour of light. Cloudy daylight tends to be blue or 'cool', candlelight is more orange or 'warm'. Colour temperature is measured in degrees kelvin (0K). Midday daylight is about 55000K and domestic bulbs are about 29000K.

A method of measuring the colour of gray at different levels from black to white. Since colour information overlays the black-and-white information in a TV signal, colour temperature affects the entire range of colour. Epson Livingstation provides five Colour Temperature settings that express the level of brightness.

Used as a method of measuring the ?whiteness? of a light source. The higher the brightness the higher the temperature. Metal halides have higher temperatures than halogens therefore have a whiter light.

The degree of blue-whiteness of light, measured in degrees on the Kelvin scale. The lower the reading the warmer or more red the light.

the quality or character of white light, measured in Kelvin (K). A low colour temperature describes a lamp with a reddish hue, whilst high colour temperatures relate to sources which look slightly bluer and (peversely) cooler. A tungsten lamp has a colour temperature of around 3000K, whilst a discharge lamp is usually in the region 5000K - 6000K. Daylight is 5600K.

a scale in Kelvins (K) - sometimes referred to as Degrees Kelvin - which measures the colour of light. A video light is 3200K, average daylight is 5-6000K, bright summer sunlit sky around 10,000K.

Colour Temperature: A method of measuring the "whiteness" of a light source. Metal halide lamps have very high temperatures compared to halogen or incandescent lights.

A method of expressing the colour content and quality of light and measured in Kelvin (K). "Photographic daylight" has a colour temperature of about 5500K. Photographic tungsten lights have colour temperatures of 3200K to 3400K depending on their construction.

The colour quality of light measured in degrees Kelvin, where )K = -273 Degrees C. Daylight colour temperature is 5600K and tungsten halogen lighting is 3200K.

Colour temperature is the colour of the hue of light emitted by a black body, such as solid carbon, heated to a very high temperature. When heated to about 1,000 degrees K, the carbon turns to a dark red colour and at 1,800 degrees K, the black carbon emits orange light with a heavy red tint. At 2,800 - 3,000 degrees K, the black carbon glows with a bright and strong reddish - white light similar to light emitted by standard bulbs know as Tungsten Lamps rated at 4,700 degrees K. The emitted white light changes its hue and peaks with yellow/green and at 7,000 degrees K, changes to blue. At 10,000 degrees K and upward, the emitted light peaks in the ultra violet and invisible range.

(also known as Kelvin temperature or correlated colour temperature) A measure of colour of light emitted by a bulb in comparison to black. This is used as a general measure of a bulb's coolness (whiter light) or warmness (redder light).

The temperature of a full radiator which emits radiation of the same chromaticity as the radiator being considered.

A comparison of the color of a light source expressed in degrees Kelvin.

A measure for lamp types, which provides a relative indication of the colour of light. It is measured in Kelvin (previously degrees Kelvin) K (213.16K=0°C).

Temperature of a blackbody that has the same (normalised) chromaticity co-ordinates as the object being studied.

The colour spectrum of a "black body" radiator heated to a given temperature on the Kelvin scale. The manufacturer's method of indicating the colour of a light source in degrees Kelvin (K); i.e. 2700K (yellow/white), 4100K (white), 5500K (blue/white).

A measure of the colour of a light source relative to a black body at a particular temperature, expressed in degrees Kelvin (°K). Low colour temperatures have a red-yellow tone; daylight has a high colour temperature (approximately 6000°K) and appears bluish.
