Consistent Control Color Across Clients

I have found that when I install and execute my VB 6.0 app on certain clients, the controls on the form are not always the same color as they are in the design environment.  Perhaps this is a consequence of the client system color settings.  Nonetheless, I am looking for a routine that will ensure the back and forecolors of my controls remain consistent with their design-time properties during execution.

Thanks.
