照明设计师们早就接受了Kruithof的建议，即温暖的照明比低强度的照明更受欢迎，而凉爽的照明比高强度的照明更受欢迎。然而，当考虑到这些对色温的偏好时，Kruithof的建议没有考虑到季节变化或年龄的差异。Kakitsuba等人（2000a, 2000b, 2003）发现，在200 lx和1500 lx的光照强度下，年龄在19 - 27岁的日本年轻受试者对色温的偏好存在季节性变化，并且与8名年龄在36 - 45岁的日本女性受试者在1500 lx光照强度下的偏好色温存在年龄差异。在这些研究之后，同样的中年女性受试者在22°C和30°C的受控室温下暴露在3000 K和7500 K的环境中。每次照明强度设置为200lx。在25°C的黑暗房间中受控暴露30分钟后，受试者暴露于给定的照明和热条件下。在整个暴露过程中测量皮肤和口腔温度、心电图和血压。每隔15分钟，受试者报告舒适度、平静度、亮度和热感觉。由此产生的HF值变化表明受试者更喜欢7500 K而不是3000 K。这表明中年女性受试者在200 lx和1500 lx的情况下都可以接受Kruithof的建议。
Lighting designers have long accepted Kruithof's proposal that warm lighting is preferred over low intensities of illumination, and cool lighting is preferred over high intensities of illumination. However, when considering these preferences in color temperatures, Kruithof's proposal does not take into account seasonal changes or differences in age. Kakitsuba et al. (2000a, 2000b, 2003) demonstrated a seasonal change in color temperatures preferred by young Japanese subjects aged between 19 and 27 under illumination intensities of 200 lx and 1,500 lx, and an age difference in preferred color temperatures when the results were compared with those obtained for eight Japanese female subjects aged between 36 and 45 under an illumination intensity of 1,500 lx. Following these studies, the same middle-aged female subjects were exposed to 3,000 K and 7,500 K in controlled room temperatures of 22°C and 30°C. The illumination intensity was set at 200 lx on each occasion. Following controlled exposure for 30 min. at 25°C in a darkened room, subjects were exposed to given lighting and thermal conditions. Skin and oral temperatures, ECGs and blood pressures were measured throughout the exposures. At 15 min. intervals the subjects reported on comfort, calmness, brightness and thermal sensations. The resulting changes in HF values indicated that the subjects preferred 7,500 K to 3,000 K. This demonstrated that Kruithof's proposal could be accepted for middle-aged female subjects in the case of 200 lx as well as 1,500 lx.
