Color spaces for the basic colors (DeviceRGB, DeviceCMYK and DeviceGray) are
created by a call to the Adobe PDF Library in this form:

"C " Example: Creating a Gray Color Space
PDEColorSpace GrayModel:
AsAtom GrayAtom;
GrayAtom = ASAtomFromName (“DeviceGray”);
GrayModel = PDEColorSpaceCreateFromName (GrayAtom);
