Workbench on Amiga 1200

You need some kind of patch which hacks into the WB's copper list and changes the palette of one pen every pixel row.

I've written one myself: http://thomas-rapp.homepage.t-online.de/downloads/wbgradient.lha

There are others on Aminet. The most famous is contained in MagicWB.

Of course you could just make a background picture which contains the color gradient you like and use this as WB pattern. But the picture will be dithered into the available number of colors which might not look like you want it to.

MagicWB is for all machines.

Yes, but the gradient utility only works with AGA chipset.

My program also works on OCS/ECS. But it needs Kick 3.0+ currently. I looked at the source code and gfx dependencies can be removed easily. The major problem is the use of the GT_GetGadgetAttrs function which does not exist in Kick/WB 2.0. I yet have to learn how to work around this.
