5700K

5700K is a correlated color temperature (CCT) used to describe the color appearance of a light source, expressed in kelvin. Color temperature indicates whether light appears more yellow/red (lower K) or more blue (higher K). At 5700K, the light is generally classified as daylight-like, lying in the neutral-to-cool daylight range. Compared with warmer white light (for example 2700K–3200K), 5700K has a slight blue cast but is still perceived as white rather than strongly blue.

In practice, 5700K is commonly used in photography, videography, and film to emulate outdoor daylight conditions or to match other daylight-equivalent sources. Many cameras offer white balance presets around 5500–6000K to approximate daylight illumination. In consumer lighting, 5700K LEDs and fluorescent lamps are marketed as daylight or cool-white options, suitable for offices, studios, and task lighting where a brighter, more clinical feel is desired.

Considerations when using 5700K include color rendering and color fidelity. The color rendering index (CRI) or similar metrics indicate how accurately colors appear under a given light; even at 5700K, light quality can vary between products. Scene appearance is affected by the interaction of the light’s color temperature with material colors and adjacent lighting. For many digital imaging workflows, 5700K can serve as a target white point, though preferences and standards vary by project.
