a Spectral dataset of sample L5 acquired at the nanosecond timescale. In the label at the bottom of each image it is reported the analysed spectral band. b False colour images: ns timescale (blue = 370–390 nm, green = 455–495 nm and red = 530–570 nm) and microsecond timescale (blue = 530–570 nm, green = 630–670 nm and red = 830–870 nm). c Reconstructed spectra in selected ROIs of the yellow, white and blue layers at different timescale, compared with reference samples from Kremer Pigmente
