Mayor Vincent Gray (above, right) and D.C. Taxicab Commission Chairman Ron M. Linton take in the display of possible taxi cab colors at Verizon Center on Monday. The District is asking for public input before it decides which color scheme will become the uniform design for all cabs in the city. Examples of four of the 10 designs (below) will move from Verizon Center to Union Station for the Inauguration and then to the Washington Auto Show before a final choice is made.
