    <title>DESCRIPTION</title>

    <para>Sets the color for drawing, filling, or both. The colorspace should
		  be one of 'gray', 'spot', 'rgb, 'cmyk', or 'pattern'. Depending on the
			colorspace either
			only the first, the first two, the first three all or remaining
			parameters will be
			used. If <parameter>colorspace</parameter> is 'pattern' then
			<parameter>c1</parameter> must contain the pattern id as returned
			by <function>PS_begin_pattern(3)</function>. If
			<parameter>colorspace</parameter> is 'spot' then the
			<parameter>c1</parameter> must contain the spot color id as returned by
			<function>PS_makespotcolor(3)</function> and the
			<parameter>c2</parameter> must contain the tint value for the color.
			</para>
		<para>The parameter <parameter>type</parameter> can be 'fillstroke', 'fill',
		  or 'stroke'.</para>

    <title>BUGS</title>

    <para>The second parameter is currently not in any case evaluated.
		  The color is
		  always set for filling and drawing just as if 'both' where passed.
			If you want to set the color to define a spot color from it, you
			will have to pass 'both' or 'fill', because
			<function>PS_makespotcolor(3)</function> utilizes the current fill
			color.</para>
