Font colour and size in emails

[mikelang]

Hi everyone,
My name is Mike and I have just purchased my ipad.
From an exisitng email that you are replying to is there a way to change the font colour and also the size of the font.
This seems like such a basic feature that is not readily available.
I know there are apps that let you write an email from their app and then it can be sent as an email.
I am not talking about this situation.
I am referring to an email I have received and want to add notes to it in a different colour and then send back.
Any ideas?
Thanks in advance,
Mike
