For energy saving in the field of architectural lighting, the daylighting technique supplemented by artificial light should be established as quickly as possible. However, it is not sufficient enough to add only artificial light for keeping mimimum illuminance level in order to secure the comfortable visual environment in architectural spaces. As the harmonization of supplementary artificial light with daylight is one of the most important problems to be examined for developing the new energy saving daylighting technique, an experimental study on the subjective preference of the colour of supplementary light emitted from four different typical and ordinary fluorescent lamps has been carried out applying an office simulated model room on a scale of 1 to 10. As the results of this research work, it is concluded that the fluorescent lamp of the type of so-called 'New Generation' (5000K) is the most desirable of the four lamps for the daylighting supplemented by artificial light in office interiors in daytime, and that the type of 'Colour Matching' or 'Daylight' (6500K) is considered to be a next alternative to 'New Generation.' The type of 'Daylight' or 'Cool White' (4200K) is evaluated less than the two types above, and the type of 'White' or 'Warm White' (3500K) is regarded not to fit for supplementary artificial lighting.
