Colour Temperature is a way of describing a colour-quality of light. It is a measure of how much light of different colours is present. High colour temperatures have a lot of blue light and low temperatures have more red light.

Techniques Glossary Colour temperature
The colour of the light source measured in Kelvin (K). Most colour films are balanced for 5500K which is the colour temperature for average daylight conditions.
Colour temperature
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.
Colour temperature.
Description of the colour of a light-source by comparing it with the colour of light emitted by a (theoretical) perfect radiator at a particular temperature expressed in kelvins (K).
Colour Temperature: A comparison of the colour temperature of a given light source, expressed in degrees Kelvin (e.g. daylight is approx. 5000-6000 degrees Kelvin) ...
Colour temperature
Measured in Kelvin, expressed on a scale (i.e.3400K) this indicates the colour content and quality of a light source light such as a lamp.
(see Tungsten film) ...
colour temperature
A measure of the colour quality of a specific light source and is measured in degrees kelvin (K).
Colour temperature
Describes the spectral energy distribution and thereby the colour quality of a light source. The temperature of a colour is given in Kelvin (K).
Light Colour Temperature
The reason that pictures turn out with a yellow/orange cast in incandescent (tungsten) lighting and bluish in fluorescent lighting is because light has a colour temperature.
What is colour temperature?
The definition of colour temperature is highly technical - it refers to the colour of light produced by a theoretical "black body" object that's heated to a certain temperature, measured in Kelvin temperature units.

Also see "colour temperature", "UV". Technically, it explained as a piece of material which restricts the transmission of radiation. Generally coloured to absorb light of certain colours. Can be used over light sources or over the camera lens.
Most importantly, watch out for a clash between the different colour temperatures of natural and artificial lighting.
Another thing which I find enhances sunset shots is to set the camera's colour temperature to ‘daylight' (or ‘flash', which is balanced for daylight).
For film cameras, professional photographers have a choice of films designed for different colour temperatures, the common ones being daylight and tungsten films.
With the optional waterproof case and Underwater mode to adjust colour temperature for more beautiful blues with easy setting, you are ready to dive into another world of photography.
I used RAW so that I could fine tune the colour temperature, contrast and exposure at the post-processing stage. It also gave me leeway in case I overexposed the photo - RAW files retain highlight detail that would be lost if you used JPEG.
Every light source has its own colour temperature, which has the potential to produce a colour cast. Setting the white balance correctly ensures that objects that are white, will appear so in the final image, for a more natural look.
Not really necessary in digital photography as the camera's white balance system adjusts for the colour temperature of the scene. You can also use them to protect the camera's lens from scratching, fingerprints or dirt.
The short flash duration enabled me to capture crisp movements of the model and the garment. Consistent flash output and colour temperature meant I could create the desired lighting effects and balance in camera without relying on excessive ...
to calibrate your monitor so that the colours you see on screen are the same as those on your transparency. For this you can use calibration software such as OptiCal 3.3. If you are using a PC, set the gamma at 2.2 and the colour temperature to 5, ...
