Mi controlador de validación:

public function store(Request $request)
{
   // dd($request->all());

    /////Validations////

    $this->Validate($request, [
        'name' => 'required|min:3|',
        'email' => 'required|unique:customers' ,
        'favorite' => 'required',
        'Password' => 'required|min:6',
        'Confirm_Password' => 'required|same:Password',
        ]);

    $user = new customer;
    $user ->name=input::get("name");
    $user ->email=input::get("email");
    $user ->country=input::get("country");
    $user ->gender=input::get("gender");
    $user ->favorite=implode(" , " , input::get("favorite"));

    if(input::hasfile("image")){
        $files = Input::file('image');
        $name = time()."_". $files->getClientOriginalName();
        $image = $files->move(public_path().'/image' , $name);
        $user->image=$name;
    }

    $user ->psw=input::get("psw");

    $user->save();
    return redirect("showall");
}

Formulario donde quiero cambiar el color de los campos:

Quiero cambiar el color del borde de los campos de entrada para cambiar el rojo cuando recibo un error de validación. Intento lo mejor que puedo pero no sé cómo solucionar este problema.
