[Groff] How to draw a colorful circle/box with colorful text

[Luke Huang]

>From the manual, I learn a way like this,

.PS
r=0.1

circle rad r "\s-2A\s+2" shaded "red" outline "green"

.PE

This works, but is not satisfying  enough for me. In this case, it draws
a circle  with green  text (what I  need) and  green edge (*NOT*  what I
need). My question is: how to draw a circle with red shade and red edge,
while the text is green?

Thanks a lot for any reply.
