Hi Sebastian,
	Just in case you mean that you are trying to color atoms and the surface is also changing, you need to restrict the coloring to just atoms.  If you are using the menus, use the "all options..." entry in the Color menu, which will allow you to restrict the coloring to just atoms/bonds.  If you are using the color command append ",a" to the color name to restrict the coloring to just atoms/bonds, e.g. "color green,a :148".
	Of course, maybe the simplest thing is to color your structure first and then compute the coulombic coloring of the surface.
