%D Colors are done with the \DVIPDFMX\ color model, which are
%D inherited.
%D Although hex colors were accommodated by Hans, we'll try the
%D more familiar \DVIPDFMX\ ones. One good side-effect of the
%D previous approach was that it kept track of the color state
%D (transparency in XeTeX is accomplished setting the color to
%D an RGBA quadruple, rather than an RGB triple). So transparency
%D will need another plan.
