Formatting Dynamically Generated Txt

hi

I am working on a mail form that passes variables and formats the users details.

The end result being a dynamic txt box (variable message2send).

What I want to do I format it so the Username, Email, Message etc are in different colours to the rest of the formatted txt.

This is the code im using (just sender name)

message2send = "Hello" <font color="#FFCC33">sender_name</font>  + Newline + " " + Newline + "You are about to send this message: " + Newline + Newline + sender_message + Newline +  Newline + "Your E-mail is: " + Newline + " " + Newline + sender_email;

Any ideas

Thanks very much
