Filmmaking Dictionary: Number 5 / 5600K Colour Temperature
Definition
5600K is a colour-temperature value commonly used as a nominal daylight reference for film lighting. The K stands for kelvin. A fixture labelled 5600K is intended to produce a daylight-like white, although its actual output depends on its design and operating conditions.
The number describes the appearance of the white light, not its brightness, power consumption or physical operating temperature. Two fixtures set to 5600K can have different output levels and can still render colours differently.
Daylight Is Not One Fixed Colour
Natural daylight varies with the sun’s position, sky conditions, shade and reflected surroundings. A 5600K lamp may be a useful starting point beside a window, but it is not guaranteed to match every outdoor source. Blue skylight, warm late sun and green reflections from foliage can coexist in one scene.
Camera white balance determines how those sources are interpreted. With the camera balanced near 5600K, a nominal 3200K tungsten source will generally appear warmer. Changing white balance shifts the whole image; it does not independently correct each light in a mixed scene.

Matching Fixtures
- Compare lights on the actual camera and recording settings.
- Check green-magenta tint as well as the Kelvin value.
- Look at skin, wardrobe and coloured objects, not only a white card.
- Repeat the comparison at the intensity and colour mode used for the shot.
Practical Lighting Example
A daylight-balanced key is used for an interview near a window, while a warm practical remains visible in the background. Keeping the key close to the window’s appearance can help the face feel consistent, while the practical provides deliberate warmth. Making every source numerically identical would remove that separation without necessarily improving the image.
If the key looks green beside the window, moving its Kelvin setting alone may not solve the mismatch. Tint adjustment or suitable correction may be needed. The colour-temperature reading is only one part of evaluating the source.

Frequently Asked Questions
Is 5600K always the correct white balance outdoors?
No. It is a common reference point. The actual light and the desired look determine the setting.
Does 5600K mean a light has accurate colour rendering?
No. Sources with similar colour temperature can have different spectral output. Test the fixture’s rendering and consistency as well as its nominal Kelvin value.
