Dvips supports one-pass multi-color printing of TeX documents on any color PostScript device. Initially added by Jim Hafner, IBM Research, @email{hafner@almaden.ibm.com}, the color support has gone through many changes by Tomas Rokicki. Besides the source code support itself, there are additional TeX macro files: `colordvi.tex' and `blackdvi.tex', and corresponding `.sty' versions for use with LaTeX.
In this section we describe the use of color from the document preparer's point of view and then add some instructions on installation for the TeX administrator.
