Small lighting knowledge | the same object under different light source illuminate why will show different color? - China lighting network

For non-luminous object, it first of all, let there be light, lighting, the human eye can observe the color of it. The object itself different wavelengths of light reflection or transmission light. The spectral composition of lighting light source and the spectral reflectance of the object itself, Or spectral transmittance) Determine the color of the object appear together. So, for sure, transform the light source, the color of the object will also be changed. Watch white cloth in the sun, for example, contains the sun within the visible spectrum from the long wave to the shortwave full spectrum composition, the sun can be referred to as 'white'. White cloth basically each wavelength of the light reflectance close to consistent, therefore, the human eye observation to white. If the white cloth to get the blue light observation, because the blue light source, lack of long wave, the reflection of light from white cloth only shortwave part, so they were observed under the light, blue calico. Similarly, observed under green light, will be green. Observed under red light, red. Therefore, lighting light source color of objects present play an important role. In the museum, shopping malls, clothing stores, such as need to accurately identify the place, pay special attention to color rendering properties of light source. YanZhiXiang
