       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 PS_makespotcolor(3) utilizes the current fill color.

       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 colorspace is 'pattern' then c1 must contain the pattern  id
       as returned by PS_begin_pattern(3). If colorspace is 'spot' then the c1 must contain the spot color id as
       returned by PS_makespotcolor(3) and the c2 must contain the tint value for the color.

       The parameter type can be 'fillstroke', 'fill', or 'stroke'.
