Font in Email and Signature Help

Hello.

I want to know if it's possible to change the font and Signature of the email accounts I have(gmail and exchange), because right now I have a blue font that I don't like and a signature that only says: sent from my BlackBerry 10.

If anyone knows something about, it'd be great.

Thanks!

If you go into your hub ,settings then email acct's ,you should be able to change it there, the font I'm not sure.
