How can i apply a CharStyle for created footnote on the fly? [CS6-jsx]

I insert footnote insted of founded text.

mSn_text = mFound[i].contents; //get footnote's content
mFound[i].contents=""; //clear contents for keeping number of future footnote 
var myFootnote = mFound[i].footnotes.add();
myFootnote.insertionPoints[-1].contents = mSn_text;
myFootnote.words[0].position = Position.SUPERSCRIPT;        
mFound[i].appliedCharacterStyle = aD.characterStyles.item(mName); 

And would like to mark footnote's numbers in text by red color (for clear view). How can i apply characterStyle or just color for footnote number in text (on the fly)? )
