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].
