How can I change the style of my dashboard based on a Excel (or any other configuration file) with the Rgbs and the images of my customer? Or there exists a better way to do it?
Then in your dashboard, set the colors of the objects you want to change so they equal the selection made in the color table. When you are changing customers all you have to do is select the new color and all your objects will change. Obviously, this is a very simple example, but it should help you get started.
