I'm trying to define a function that is of this form:

f1[gr_,clr_] := Graphics@Style[gr,clr]

f2[gr1_, clr1_, gr2_, clr2_ (*etc*)] := Show[{f1[gr1,clr1], f1[gr2,clr2] (*etc*)}, "showOpts"]

Ηere, gr is a defined graphic, and clr is a color. I'm trying to have the arguments in f2 not require braces, just like one would use arguments in Graphics. I already have options for Show that are the same for every iteration of f1, but I'm having trouble with sequencing this one. `

    $\begingroup$ f2 = List /* OperatorApplied[Partition][2] /* Map[Apply[f1]] /* Show. $\endgroup$ Nov 1, 2021 at 17:38
  • $\begingroup$ I'm not sure I entirely follow. Graphics takes one argument, a list of styles and objects, not a var-arg" $\endgroup$ Nov 1, 2021 at 21:58

ClearAll[f1, f2]
f1[gr_, clr_] := Graphics@Style[gr, clr]

f2[args : __, opts : OptionsPattern[Show]] := Show[f1 @@@ Partition[{args}, 2], opts]


f2[Disk[{2, 2}, 1], Red, 
 Annulus[{1, 1}, 1/2], Blue, 
 Rectangle[{0, 2}], Green, 
 ImageSize -> 400, Frame -> True]
