Can anyone tell me how to create a .pz2 that will just change the kd color without removing all of my shaders?

I already have a pz2 that has all of the kd color statements only and it works. But I need to know if there's a line I can add that will tell Poser to leave the textures and shaders alone and just change the kd color.

All I want to do is have a pz2 to alter the shade of the existing textures.

Anyone know how to do this, thanks in advance.
