The spectral variability in the color-color diagram in Quasi-Periodic Oscillation (QPO) sources is discussed. The blackbody spectra comptonized by a hot electron plasma also fit the EXOSAT spectra of these sources. A parametrization of the color-color diagram indicates systematical parameter variations in all spectral branches. They can be decomposed in a variation of a single photon source and an extended hot electron cloud. The temperature of the photon source varies between 0.5 and 1.0 keV, the electron cloud has scattering depths between 3 and 7 and temperatures from 2.0 to 5.0 keV. Links to QPO models on the horizontal spectral branch and physical consequences of the model are discussed.
