Configuration Specific Color not working

Hello:

   I'm having a problem where I have 5 configurations of a part. I want to change the color of the 5th one to gray, while the other 4 stay black.

I go into the configs., right click, on it, & choose properties, then I go down & check use configuration specific color, change the color there, but  it

changes the color in all of the configurations. Seems to me like the confuration specific color, isn't working. What might I be doing wrong? Or is this some

kind of gliche.

Thanks in advance;
