Default Need Help with Keyboard theming

Hello everyone. I recently posted this in my pull downs and fw backgrounds question but didn't know if anyone would see it so I'm posting it here as well. I'm looking to theme a keyboard. A Samsung note 3 keyboard to be specific. I have read many how to guides but I must be to much of a noob to understand lol. I would like to add some color to the keyboard. If anyone could help me out it would be greatly appreciated!
