Ayuda con programa C#

[frandy_Javier]

Necesito crear un programa que contenga un boton para crear labels y botones entre otros componentes C# dependiendo de radio boton, sucede que he podido crear los botones con sus funcionalidades excepto el de cambiar color, debo crear un boton cambiar color que permita seleccionar todos los botones o label que existan en el form y les cambie el color.... Podria alguien ayudarme con una funcion para cambiar el color de todos los objetos creados en el form...

Gracias!!!!
