Enum class only available with -std=c++11

So I was trying to learn Enum classes. I copied this piece of code into my compiler:

#include <iostream>
using namespace std;
int main()
{
  enum class Color
  {
    RED,
    BLUE
  };

  Color color = Color::RED;

  if (color == Color::RED) 
    cout << "The color is red!\n";
  else if (color == Color::BLUE)
    cout << "The color is blue!\n";

  return 0;
}

I expect the code to print out "The Color is red!" However, my compiler gives this error:

warning: scoped enums only available with -std=c++11 or -std=gnu+11

and

error:'Color' is not a class or namespace

I'm currently using Dev-C++5.11. Any idea how to fix this?
