The image is of a flag, representing the Earth.  It has an overall dimensional ratio of width: three, and length: five.  It consists of a field of blue (web color #0000CC definitive, PMS Blue 072 C suggested), in the center of which is a circular ideographic symbol for the Earth as the flag's charge.  The ideogram depicts a stylized cartographic projection (Nicolosi globular) and is rendered in white lines (web color #FFFFFF) over the field of blue.  The diameter of the charge is 2/5 of the flag's total length.  The thickness of the charge's lines is 1/20 of its overall diameter. (See construction sheet.)
