Refresh - Logo and Stationery

This time i had an order from my friend to help him designing logo and other stationery tools such as letterhead, envelope, and bizcard. It's a startup company, so i have to make the design from the scratch to this.

The company name is Refresh, with one holding and for the unit below the business. So the logo have to be formal, corporate like, and show the fresh itself.

And the result, is a unique logo with customizable nice colors for every company below the holding. The logo tells different colors to describe its business. The gradient colors means that every business has its own steps..gradually to become solid. And the shape forms from 4 smaller shapes describing the symbol of vision of an eye. That symbol also become a trademark to every stationery applied theme.
