Hi Siriam, If you want to get the colorspaces of objects on a page, you might want to look at podofocolor from the podofotools package. It extracs colorspace information from the content stream of a page.
But, be aware that the whole topic is far more complex than just getting the colorspace of a page - as Leonard has pointed out.
