how to change a color in listbox

Question

hello
I am building a chat client with a listbox
I want that each client will choose his own text color in the chat
I did it in this way:

 void cc_ReadMsgEvent(MessageFormat card)
    {
        UpdateListBox(card.ToString());
        listBox1.ForeColor = card.myColor;
      }


However, when I do it, it changes the color of all the text in the listbox,  and I want to change the color
only of one line each time.    how can I do it ?

thank you
