We present a novel extended colour space for low- dimensional spectral colour management, coined LabAB. We discuss design goals and perform a comparison of sev- eral approaches to fuse the perceptual information engen- dered by several illuminants. Results indicate that, with only five dimensions, LabAB conveys significantly no less perceptual information on average than state-of-the-art rep- resentations such as the interim connection space LabPQR. We also demonstrate that LabAB can be used for spectral vector error diffusion.
