Details of the visible image and key spectral features of paints denoted as green1 and green2. a XRF spectrum representative of green1; b UV–Vis-NIR reflectance spectrum representative of green1 compared with a reference spectrum of viridian (differences at short-wavelengths could be due to a not identified pigment/extender absorbing in this spectral region; c Raman (λexc = 785 nm) and d UV–Vis-NIR reflectance spectra representative of green2, both compared with reference spectra of a phthalocyanine green standard
