I am dabbling with postscript. I like it, but it take a lot of
time. ;-)

The last 6 graphics at:
    https://www.facebook.com/media/set/?set=a.351549161549364.70328.100000828491269

(the first 6 in the list) I made with postscript. But I see some noise
in some of them. How can I circumvent this. At the moment I use ps2pdf
to make an pdf and then convert (from Image Magick) to make a png. I
saw that it is in principal possible to make a png with ghostscript.
Would that give better results.

My second question is about colours. As you can see from the pictures
I am not the worlds greatest graphics designer. What are good
resources to learn about good colour combinations? (Maybe good
resources about typography would not be wrong also.) But for a newbie
of-course. :-D
