Hm. Then I'd make it a macro:

#macro MyTorus_Macro(Light_Color)
#declare MyTorus=[...]
[In the lightsource, put "rgb Light_Color"]
object{MyTorus}
#end

MyTorus_Macro(Blue)
MyTorus_Macro(Orange)

If you'd want to move it around, you can just add
another parameter to the macor:

#macro MyTorus_Macro(Light_Color,Position)
#declare MyTorus=[...]
object{MyTorus translate Position}
#end

Regards,
Tim
