Can anybody help????

Does anybody know how to set the pdf "Colour" or "Black & White" option using a vba macro?

I have already created a vba macro that creates a Pdf file every time the user presses "Save" when in a "SldDrw" (drawing) document.

I want to output "Black & White" Pdf files for detail drawings and "Colour" Pdf files for assemblies.

Many thanks in advance!!!!
