Off the Planckian Locus: Using 2D Chromaticity to Improve In-Camera Color

ArXi:2511.17133v3 Announce Type: replace Traditional in-camera colorimetric mapping relies on correlated color temperature (CCT)-based interpolation between pre-calibrated transforms optimized for Planckian illuminants such as CIE A and D65. However, modern lighting technologies such as LEDs can deviate substantially from the Planckian locus, exposing the limitations of relying on conventional one-dimensional CCT for illumination characterization.
