Help on Dictionary copy

Code:

// create dictionaries
    public Dictionary<string, int> colors = new Dictionary<string, int>();
    public string color; // name for dictionary
   
    public Dictionary<string, string> geneo = new Dictionary<string, string>();
    public string gtype; // name for dictionary
    
 // create unlinked dictionaries
        public Dictionary<string, string> geneo2 = new Dictionary<string, string>(); // Unlinked
        public string gtype2; // name for dictionary
        public Dictionary<string, int> colors2 = new Dictionary<string, int>(); // Unlinked
        public string color2; // name for dictionary

This is where I run into problems

Code:

            // copy dicitionaries
            Dictionary<string, int> colors copy = new Dictionary<string, int>(colors2);

What is the correct syntax?

Code:

Dictionary<string, int> colorsCopy = new Dictionary<string, int>(colors2);

Code:

colors copy

is not a valid identifier name.
