Impossible materials – simulated

by adrien

I played around with the measured spectra of my Epson and simulated materials colours that strongly switch hue when the colour temperature of the light source changes. The materials are impossible because the spectrums are either emissive (higher than 100% reflection, like fluorescent materials) or have negative values. The results are funny since they look like natural colours close to some exotic flowers or to some “birds of paradise”.
