The theme - Arona is made with that in mind that it has to be very easy to work with.
The whole theme is transparent, meaning that the background color will shine through the buttons!
Another great thing about the theme is that there is only three (3) backgrounds you will need to alter to change the theme to your customers color scheme. That is the background color on the page master and the top ribbon on the master as well. Then, also change the background on the Main Page.
To complete the branding, just replace the top left button with the customers logo!
Changing the buttons, giving them new names, or a symbol is just as easy as always.
