I am. Thankfully the blue seems to be dying out as the old guys leave, at least in my area.

Well it's a replica of ERAM and VSCS. ERAM is En Route Automation Modernization and in simple terms, it is the radar system used at FAA ARTCCs. VSCS is Voice Switching and Control System and from the controller's perspective, its the touch-screen display that allows manipulation and use of frequencies and ground-to-ground shout, override, and dial lines to communicate with other controllers and facilities (again, this is FAA software/hardware). But most importantly, never trust a controller with their ERAM prefset that has their scope that blueish color. Black is the only way to work.
