colorSpec: Color Calculations with Emphasis on Spectral Data
Calculate with spectral properties of light sources, materials, cameras, eyes, and scanners.
Build complex systems from simpler parts using a spectral product algebra. For light sources,
compute CCT, CRI, SSI, and IES TM-30 reports. For object colors, compute optimal colors and Logvinenko coordinates.
Work with the standard CIE illuminants and color matching functions, and read spectra from
text files, including CGATS files. Estimate a spectrum from its response. A user guide and 9 vignettes are included.
