The mark consists of a black, stylized capital letter "G" in the forefront, superimposed centrally on an unlabeled, gradient green-filled, black-outlined map of Brooklyn, New York. The green fill is gradient by which the darkest shades of green are near the perimeter of the map, becoming lighter toward the center of the map (and as such, the center of the literal mark "G") which contains the lightest shade of green, almost white, to imitate a central glow, radiating outward. In the background is a circular shading or shadow of light grey, upon which the green-filled map of Brooklyn rests. Also included in the circular grey shaded background layer are light grey outlines of Brooklyn, outside the black border of the Brooklyn map, adding depth to the image, making it appear slightly three-dimensional.
