The color(s) purple and blue is/are claimed as a feature of the mark.
The mark consists of the word "Gamma" comprising a capital letter "G" with the remaining letters in lower case, all of the letters being blue in color, and a spherical design disposed to the left of the capital letter G, the spherical design comprising a center shaded circle and three concentric rings of circles surrounding the center shaded circle, wherein the circles in the first and closest concentric ring are each shaded and smaller than the center shaded circle, the circles in the second concentric ring are each shaded and smaller than the circles in the first and closest concentric ring, and the circles in the third concentric ring are each shaded and smaller than the circles in the second concentric ring, the circles in each concentric ring being arranged to create an illusion that the entire design is spheroidal in configuration, the shaded circles all being purple in color.
