Sprinkle raspberry gelatin and unflavored gelatin over 1/2 cup cold water in a large saucepan; stir and let stand 1 minute.
Cook over low heat, stirring until gelatin dissolves (about 2 minutes). Stir in cranberry mixture, oranges, and next 3 ingredients. Cool to room temperature. Stir in marshmallows, and pour into a 13- x 9-inch pan. Chill 8 hours.
