It can be applied to Flash projects, the colors and fonts being customizable.
Adobe Flash components enable you to build complex Flash applications, even if you don't have an advanced understanding of ActionScript. Rather than creating custom buttons, combo boxes, and lists, you can drag these components from the Components panel to add functionality to your applications.
Download and unzip the M1Theme package.
Select File > Open to open an existing Flash document, or select File > New to create a new one.
Select File > Import > Open External Library. Browse to your unzipped M1Theme folder and open M1Theme.fla.
In the M1Theme.fla's Library panel, select "M1 Theme" folder and drag it to the Library panel of your Flash document. This will automatically assign the theme to the components in the document.
From your unzipped M1Theme folder copy a folder named m1 and paste it in the deploy folder of your project. The deploy folder is the folder where your .swf file is. By default it is in the same folder as your .fla file.
