= Kruithof curve
{wiki=Kruithof_curve}
The Kruithof curve is a graphical representation that illustrates the relationship between the color temperature of light sources and the perceived brightness or illuminance of those sources. It helps to guide the selection of lighting based on the combination of color temperature (measured in Kelvin) and the illumination level (measured in lux). The curve itself indicates that: 1. **Lower color temperatures (warm white light)** can create a pleasant atmosphere at lower illumination levels (e.g., around 200 to 300 lux).
