- Kruithof_curve abstract "The Kruithof curve describes a region of illuminance levels and color temperatures that are often viewed as comfortable or pleasing to an observer. The curve was constructed from psychophysical data collected by Dutch physicist Arie Andries Kruithof, though the original experimental data is not present on the curve itself. Lighting conditions within the bounded region were empirically assessed as being pleasing or natural, whereas conditions outside of the region were considered uncomfortable, displeasing or unnatural. The Kruithof curve is a sufficient model for describing pleasing sources that are considered natural or closely resemble Plankian black bodies.For example, natural daylight has a color temperature of 6500 K and an illuminance of about 104 to 105 lux. This color temperature-illuminance pair results in natural color rendition, but if viewed at a low illuminance, would appear bluish. At typical indoor office illuminance levels of about 400 lux, pleasing color temperatures are lower (between 3000 and 6000 K), and at typical home illuminance levels of about 75 lux, pleasing color temperatures are even lower (between 2400 and 2700 K). These color temperature-illuminance pairs are often achieved with fluorescent and incandescent sources, respectively. It is noteworthy that the pleasing region of the curve contains color temperatures and illuminance levels comparable to naturally lit environments.".
