(* I have two suggestions for you: Button[] and Mouseover[] *)
(* First using Button[] and Dynamic[] *)
even1 = True;
even2 = True;
Graphics[{
Button[{Dynamic[If[even1, Red, Yellow]], Disk[{1, 1}, 0.5]},
even1 = Not[even1]],
Button[{Dynamic[If[even2, Green, Brown]], Disk[{2, 2}, 0.5]},
even2 = Not[even2]]
}]
(* Second using Mouseover[]. It is not exactly what you asked for, but it
might be useful for you *)
Mouseover[
Graphics[{Red, Disk[{1, 1}, 0.5]}],
Graphics[{Yellow, Disk[{1, 1}, 0.5]}]
]
(* I hope it helps *)

Asunto: [mg87435] Event when clicking one of many Disks in a Pane
Can someone help me figure out how to use EventHandler
to evaluate an expression when one of many Disk[]
objects in a Graphics Pane is clicked.
For example suppose I create a red and green disk in a
graphic:
Graphics[{Red, Disk[{1, 1}, 0.5], Green, Disk[{2, 2},
0.5]}]
Each disk is a separate and editable object in the
graphics pane. Can I therefore associate an Event with
a Mouseclick on each disk? To make matters simple lets
say the disk change color from Red to Yellow and Green
to Brown.
