Absorption Spectrum of Pigments

Compare and contrast the absorption spectrum of pigments of Cyanobacterium vs. the various purple bacteria. What wavelengths are preferentially absorbed by the pigments of each group of bacteria & how do the absorption properties of these molecules compare with the regions of the spectrum visible to our eye? How do they explain the predominant color of each group of bacteria?
