That gives a gradient fill. I mean more something like:
    %!PS-Adobe-3.0 EPSF-3.0
    %%BoundingBox: 0 0 300 450

    1 1 1 setrgbcolor
    0 0 300 450 rectfill
    1 0 0 setrgbcolor
    100 350 100 50 rectfill
    1 0.5 0 setrgbcolor
    100 300 100 50 rectfill
    1 1 0 setrgbcolor
    100 250 100 50 rectfill
    0 1 0 setrgbcolor
    100 200 100 50 rectfill
    0 0 1 setrgbcolor
    100 150 100 50 rectfill
    .31 0 .5 setrgbcolor
    100 100 100 50 rectfill
    .94 .5 .94 setrgbcolor
    100 50 100 50 rectfill
    showpage

But then only for the object drawn, for example some text.
