Clipping mask problems with lightning image brush? Not working

Hi. I am using a lightning brush in photoshop and I am trying to colorize it and attach this color via a clipping mask to the brush layer only but it does not work? I can colorize the entire image but when I go to clip this color layer only to the brush layer nothing happens and the brush layer appears to not be affected. Same for when I try to make other adjustments and clip them only to this brush layer, contrast etc. Would anyone know why this might happen?
