Hi Mojca,
this is also on my wishlist (and christmas is over). Currently I use several color gradients in a row, to simulate the same effect. But sadly this way is too viewer dependent (rendering is a matter of luck with every new version), not to mention the big size. So if there would be a cleaner solution, I would be a happy man.
I'm willing to help, but I haven't looked into specials yet. Give me some time for reading and some more time for understanding... ;)
With Hans's hint I finally got some kind of result. However, the numbers in the stream seem to influence the colors, but not in the way I want them to. I have to do some further explorations. Does anyone know how to convert PS to PDF without compression? Btw: TikZ supports such shadings, so if you don't necessary need a metapost graphic, you can take a look at it as well. Here's an example from the manual: \usemodule[tikz] \starttext \pgfdeclarehorizontalshading{myshadingA} {1cm}{rgb(0cm)=(1,0,0); color(2cm)=(green); color(4cm)=(blue)} \pgfuseshading{myshadingA} \stoptext (I've just found out that it uses another aproach for "sampled functions", perhaps I'll have more chances to figure out how to implement it that way.)
