The whole idea behind the ‘Double Dip’ cases is to be able to customize the looks of your HTC One using different colors for the top, middle, and bottom parts. The approach is similar to that of Motorola with its fully customizable Moto X, but for the HTC One we are only talking about changing the looks via a case, not via a full repaint of the device.
With 6 color choices and 3 parts to customize, you can’t complain about lack of variability, though. Actually, a whopping 216 color combinations are possible with the new cases! Take a look at some of them right below, and hit the source link to combine one yourself. HTC has set the price of a ‘Double Dip’ case at $30.
