Hi Rubi,
If you're just talking about color, then it's yes.
But if you're talking about the "3D" form, then it's much more complicated to do. Not for drawing but for adjustment.
To have a "3D" shape, I need more space. And the place is not there. In this case, it would be necessary to reduce all the elements which constitute the roundabout.
And therefore also decrease the output numbers that appear in the center of the roundabout.
It would require a lot of testing and time ................
