Everytime you change the color you send the event function:

Code:
//Do it on the player that changed the color!

//I used event number 20 for the change color event:
enet_svset_event(20,_str("change_color_event"));
enet_clset_event(20,_str("change_color_event"));

//do this for changing into yellow:
enet_clsend_event(20,_str("y"),-1);
//do this for changing into blue:
enet_clsend_event(20,_str("b"),-1);
//and so on.

//This function will be called on all participants when you use the enet_clsend_event(20,...); function:
function change_color_event(var sender, STRING* msg)
{
   if(str_cmp(msg,"y") == 1)
   {//yellow
   }
   if(str_cmp(msg,"b") == 1)
   {//blue
   }
   //and so on
}
