It is called the "Blue Area" because it was represented in a colour blue in the original design of the planned city. The area is actually a corridor that runs along Islamabad's Khayaban-e-Quaid-e-Azam, Islamabad's primary arterial road which leads up to the main government buildings. It is characterized by clean, wide roads and tall buildings among the panaromic greenery of the adjacent areas. Recently, construction began on The Centaurus, a multi-purpose complex in the Blue Area which will include residential and office towers, and a luxury hotel.
