Components colors in parts/assy

Hello;

      Wondering whats going on with the colors. I change the color in the part through the options/document/colors/shaded. Then when I go to the assembly the colors haven't updated. Then I select the component & r.c. the ball & get a color chart in the assembly. It accepts the change in the context pop up,(you see the color change), but the component in the assy still doesn't change. All the components are the same material & I don't know exactly what that's going to be yet. I want contrast in the colors for the components as viewed in the assy. at this point. 

       Thks for any help in advance.
