dynamic text colour change

By teamchuck | Jan 12, 2009

Using this code I am filling a dynamic text box with numbers 1-number defined by xml:

Code:

var pageNum:String;

txt.text = "";

for (var i:int=1; i < myXML.*.length()+1; i++) {

        pageNum = String(i);

        txt.appendText(pageNum+"   ");

}

What I would like to do is be able to change the colour of one number. If the dynamic text box has the numbers 1-5 in it I would, for example, like to change the colour of the number 2. Have it set to blue but the rest to white. How would I do this without changing the colour of the entire text field?
