+%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.

+% Although in \CONTEXT\ transparency is closely integrated
+% in the color drivers, in the end it is an independent
+% feature.
