许多国家照明标准的一个特点是建议高相关色温的灯不应在低照度下使用。这一建议的技术理由是有限的，因此进行了两个实验来探索其有效性。在第一个实验中，15名观察员进行了颜色辨别任务，并评估了一个小房间的照明照明不同的照度使用灯具有良好的显色性能，但具有不同的相关色温。房间的装饰是无色的，但自然的颜色，以水果和鲜花的形式，被引入作为另一个变量。在第二个实验中，10名观察员进行了颜色辨别任务，并对同一个房间的照明进行了评估，该房间的照明亮度为225勒克斯，但装饰有蓝色或粉红色的墙壁，并由具有良好显色性能但不同相关色温的灯照亮。同样，以水果和花朵形式出现的自然颜色也被作为另一个变量引入。对房间照明评估的分析表明，决定照明印象的一个主要因素是照度。增加照度使房间的照明看起来更愉快，更舒适，更清晰，更刺激，更明亮，更多彩，更自然，更友好，更温暖，更均匀，更少朦胧，更少压迫，更少昏暗，更少敌意。所使用的灯的相关色温实际上对观察者对房间照明的印象没有影响。影响房间照明效果的另一个主要因素是自然色彩的存在。以水果和鲜花的形式引入自然色彩，增强了照明所产生的积极印象，特别是在较高的照度下。这种增强与所使用的灯的相关色温无关。可以得出结论，建议限制使用高相关色温灯在房间照明低照度是不合理的限制。所获得的结果表明，提供的居住者是完全适应照明的灯的相关色温对人们的印象的房间的照明的影响不大。
A feature of many national lighting standards is the recommendation that lamps with high correlated colour temperatures should not be used at low illuminances. The technical justification for this advice is limited so two experiments have been conducted to explore its validity. In the first experiment, fifteen observers carried out colour discrimination tasks and assessed the lighting of a small room lit to different illuminances using lamps with good colour rendering properties but with different correlated colour temperatures. The room decor was achromatic but natural colour, in the form of fruit and flowers, was introduced as another variable. In the second experiment, ten observers carried out colour discrimination tasks and made assessments of the lighting of the same room lit to 225 lx, but decorated with blue or pink walls and lit by lamps with good colour rendering properties but different correlated colour temperatures. Again, natural colour, in the form of fruit and flowers, was introduced as another variable. Analyses of the assessments of the lighting of the room showed that one major factor determining the impression given by the lighting was the illuminance. Increasing the illuminance made the lighting of the room appear more pleasant, more comfortable, clearer, more stimulating, brighter, more colourful, more natural, more friendly, more warm, more uniform, less hazy, less oppressive, less dim and less hostile. The correlated colour temperature of the lamps used had virtually no effect on the observer's impression of the lighting of the room. The other major factor influencing the impression of the lighting of the room was the presence of natural colour. Introducing natural colour, in the form of fruit and flowers, enhances the positive impressions created by the lighting, particularly at the higher illuminances. This enhancement occurs regardless of the correlated colour temperature of the lamps being used. It can be concluded that the advice limiting the use of high correlated colour temperature lamps in rooms lit to low illuminances is unnnecesarily restrictive. The results obtained suggest that provided the occupants are fully adapted to the lighting the correlated colour temperature of the lamp has little effect on people's impressions of the lighting of the room.
