Description

The below code (from page 140 of the original Amos manual) draws a red rainbow on screen:

Set rainbow 0,1,64,"(8,2,8)","",""
Rainbow 0,56,1,255
Wait Key

This works on AOZ but the rainbow is so dark it's barely visible.

You have to be in Amiga mode to run such examples, in Amiga mode, colors are in the form $RGB whereas in AOZ mode, $RRGGBB.
If you want this example to work in AOZ mode, you should replace the string with:
Set rainbow 0,1,64,"(8,20,8)","",""

Even in the "amiga" manifest the rainbows are really messed up.
Here's an example of what the above example produces.

The lines are offset, and there are gaps at irregular intervals.

The short color problem is now fixed in the rainbows.
But rainbows need a refactoring to avoid gap, that only happen in full screen where there is too much data to handle. For a next version.
