Earth Flag: The image is of a flag representing Earth, her diverse communities of people, and all of her forms of life. The flag has an overall dimensional ratio of width: three, and length: five. The flag’s background is divided into two fields, per bend sinister, the upper-hoist field being black (web color #000000, PMS Black 6 C) and the lower-fly field being yellow (web color #FFFF00, PMS 803 C). In the center of the flag, overlapping the fields, is a large blue roundel (web color #0000FF, PMS 2736 C) with a light-blue crescent (web color #00AAFF, PMS P 115-7 C) describing its fly-side limb. The diameter of the blue roundel is two-thirds of the flag’s vertical width. Within the flag’s upper-hoist canton is a smaller gray roundel (web color #555555, PMS P 172-14 C) with a white crescent (web color #FFFFFF) describing its fly-side limb. The diameter of the gray roundel is two-elevenths of the flag’s vertical width. Each roundel’s crescent, the concave edge whereof describes a semi-ellipse, is orthogonally oriented and has a width that is, at its widest, one-fourth of the diameter of its respective roundel. Both roundels are the same distance from the top of the flag: one-sixth of the vertical width of the flag, which is also the distance from the blue roundel to the bottom of the flag. The gray roundel is that same distance from the hoist: one-tenth of the horizontal length of the flag. The blue roundel represents the Earth, the gray roundel represents the Moon, and the yellow field represents the edge of the Sun. The gray roundel is three-elevenths of the diameter of the blue roundel, corresponding to a fairly accurate ratio of the actual sizes of the Moon and the Earth. The image was created using Inkscape and is in the public domain. The RGB hexadecimal colors are definitive; the PMS colors are suggestions. (See construction sheet.)
