We introduce a source color model as a simple extension to the {CICAAR} which allows for a more parsimoneous representation in many practical mixtures. The new filter{-CICAAR} allows Bayesian model selection and can help answer questions like: 'Are we actually dealing with a convolutive mixture?'. We try to answer this question for {EEG} data." }
