(a) Calculated absorption spectra of the dimer as a function of the photon polarization axis. (b) Perceived colour for the polarization axis at −45° against the b-crystallographic direction in the (001) plane (orange–red). (c) Perceived colour for the polarization axis at +45° (yellow). The crystallographic and polarizer directions are the same as in Fig. 5[link].
