Casting int to enum.

Hello guys,
I have a quick question regarding enums. I have an enum called test which is made of multiple colors as shown. I want iterate using a for loop from i=0 to or from 4 to zero or whatever and I want to print the corresponding color name.
Can it be done using casting. I know I can print the corresponding number to each color what I want to do is print the color name corresponding to a certain number from 0 -4. I tried casting but I just get the integer values.

thanks

  #include <iostream>
using namespace std;
enum test
{
    red,
    blue,
    green,
    black,
    white,
};

int main(int argc, const char * argv[])
{
   
    for (int i=0;i<4;i++)
    {
        
        
        test castenum = (test)(i);
        cout<<castenum<<endl;
      
    }
    
    return 0;
}
