We study the quantification of whiteness perception under illumination from various light sources. We discuss an existing metric for sources with high correlated color temperature (CCT), CIE whiteness, and propose a procedure to adapt it to sources of any CCT. We illustrate our approach by comparing the ability of different warm-white sources to render whiteness. We show that a careful engineering of the spectrum -facilitated by the flexibility of light-emitting diode sources - is essential to render whiteness.
我们研究了在各种光源照射下白色感知的量化。我们讨论了一种针对高相关色温（CCT）光源的现有度量标准——CIE白度，并提出了一种使其适用于任何CCT光源的方法。我们通过比较不同暖白色光源呈现白色的能力来说明我们的方法。我们表明，借助发光二极管光源的灵活性对光谱进行精心设计对于呈现白色至关重要。
