The mark consists of the stylized initials "HX" in shades of charcoal and white superimposed over an atom-like design consisting of three overlapping ovals and seven spheres. The ovals appear in both light and dark charcoal and have a double border, with the outermost oval lighter in color than the inside oval. Six blue and white spheres mark the outer intersections of the ovals. The color in each of the spheres is darker blue on the outside, fading to white in the center. One charcoal sphere, fading to white in the center, appears directly over the letter "X".
