[support] BUEditor buttons

Hello Friends, I wish to use BUEditor for my web site as because this is only RichText Editor which allow me to use my Language Java Script. So I wish to use this Editor. Now I have install new Module of Bueditor, but there are some buttons missing. and I need two of them. 1) Font Color Button 2) Text-Background Color Button. I have seen these two buttons on some other sites and they are working very good. I got that java Script called as "default_buttons_functions" but I dont know how to add button code. Anyone please help me.... I am attaching the pics and that java script with this. Thanks.
