RESUMO

Inexistent colors have been the inspiring theme of investigation by Israel Pedrosa, a Brazilian artist, who has devoted his life to creative painting, exploiting the chemical and physical effects associated with light, especially those generated in the light refraction domain. In this article, by focusing on the electronic spectra of phthalocyanines and gold nanoparticles, we discuss how such effects can influence the spectroscopic measurements, leading to inexistent bands and transitions.
