	ColorDialog^ colorDialogue =gcnew ColorDialog();
	try
	{
		
		colorDialogue->AllowFullOpen =true;
		colorDialogue->AnyColor = true;
 
		if(colorDialogue->ShowDialog() ==::DialogResult::OK)
		{
			str =  colorDialogue->Color.ToString();
		}
		
	}
	finally
	{
		if(nullptr!=colorDialogue)
		{
			delete colorDialogue;
			colorDialogue=nullptr;
		}
	}
	return str;
 
}

The code looks OK.
(I think the finally block is redundant but it should not cause problems).

I don't see why it should not work.


You could give this a try
String^ Colour()
{
        ColorDialog^ colorDialogue =gcnew ColorDialog();
        try
        {
               
                colorDialogue->AllowFullOpen =true;
                colorDialogue->AnyColor = true;
 
                if(colorDialogue->ShowDialog() ==::DialogResult::OK)
                {
                       return  colorDialogue->Color.ToString();
                }
               
        }
        finally
        {
                if(nullptr!=colorDialogue)
                {
                        delete colorDialogue;
                        colorDialogue=nullptr;
                }
        }
        return String::Empty;;
 
}

the above solution is like this.

String^ Colour()
{
String^ str =String::Empty;
       ColorDialog^ colorDialogue =gcnew ColorDialog();
       try
       {
               
               colorDialogue->AllowFullOpen =true;
               colorDialogue->AnyColor = true;

                if(colorDialogue->ShowDialog() ==::DialogResult::OK)
               {
                     str= colorDialogue->Color.ToString();
               }
               
       }
       finally
       {
               if(nullptr!=colorDialogue)
               {
                       delete colorDialogue;
                       colorDialogue=nullptr;

Isn't that what you posted initially and said did not work?

If it does not work have you tried my suggested code ?  (I don't see any obvious mistake in your code but if it doesn't work then it does not work ! )

I've just done a simple console app.
Your code functions - I see the color dialog twice.

Using the following I also see the color dialog twice:

String^ Colour()
{

       ColorDialog^ colorDialogue =gcnew ColorDialog();
       try
       {
               
               colorDialogue->AllowFullOpen =true;
               colorDialogue->AnyColor = true;

                if(colorDialogue->ShowDialog() ==::DialogResult::OK)
               {
                      return  colorDialogue->Color.ToString();
               }
               
       }
       catch(Exception^ e)
       {
       }
         return String::Empty;;

 
}

int main(array<System::String ^> ^args)
{
String^ str1 =Colour(); //First time it is opening
String^ str2=Colour();//Again the colour dialog opens
return 0;  //breakpoint here - str1 and str2 containing DIFFERENT values based on what I have selected
}
