I think you can
AREA:60
AREA:20#fffc00::STACK
AREA:20#f00::STACK

find nicer colors, softer, probably with an alpha part as well, e.g. #F004 
for red.

The first area is invisible, just creates a platform for the next one.
Then stack 20 high in yellow, then 20 in red.

And also see the tutorial for this. I think there's an example of this in it 
as well, although it doesn't use the newer features like using fixed amounts 
instead of (C)DEFs.
