The Spectra artworks emit and absorb light showing a gradual transition between different values. In physics, spectra represent energy emission as lines, with the intensity of the line represented by the brightness and width of the line. A stellar spectrum can reveal many properties of of astronomical objects, such as their chemical composition, temperature, density, mass, distance and luminosity. The emotional spectrum reflects countless feelings experienced by human beings- ranging from positive sensations such as joy and love to negative states often triggered by fear, anger or sadness, and everything in between.
