How to change the color of an element without moving it into new collector ?

Hi,

i have to diplay the hexa elements in a model in four different colors based on some conditions.

Is it possible to give temporary colors to elements so that at the end of macro their colors again to be reset.

and main thing is i have to give colors without moving them into newly created collectors of corresponding colors.

i am not able to give *colormark as it not supports for elems. any command for that ?

any one help me.
