Why activated carbon absorbs colored particles? Why colour matters?

    Seems a bit odd why colour determines if it is absorved or not, doesn't it? My teacher could not answer this question.

    Color doesn't matter, carbon absorbs any molecules. We just do the simple experiments with colored substances as then the change is easy to observe.
