Abstract

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.

  23. Indeed, ω represents the relative sensitivity of luminance factor Y and blue-shift to whiteness. In our samples the value of Y barely depends on the source, only the color shift is significantly different. Therefore a change in ω would rescale the whiteness values but would not change the relative rankings of whiteness under the different sources. Regarding φ, its value has a very small numerical effect so long as it is close to 0°, as discussed in [1].
