English: There are many renditions of the Yin-Yang symbol, but none is truly/officially standardized/definitive. This one uses the two-circles-in-a-main-circle technique, a "reversed-S" curve separating Yin/right from Yang/left. Inside the Yin/Yang circles are vertically-oriented (instead of horizontally, or any other) squares (instead of circles), with sides 1/6 the diameter of the main circle, thereby creating completely separated "broken lines" (and hence evoking I Ching hexagrams generally, and particularly: (i) ䷝ radiance, clinging fire, the net; (ii) ䷼ center returning, inner truth, central return). Typical/classical black-and-white aren't really most appropriate, because the such renderings need to use some kind of "rim" (typically black) separating black/white, thus unbalancing yin-likeness vs. yang-likeness. So we must use some non-black/white, i.e., color. The colors used in the present rendering are precisely the 27 principal/canonical RGB colors (where each of the R/G/B octets has value 0x00/0x80/0xff, three of them being white/gray/black). It is preferable to use these discrete colors, rather than a continuous set of colors, to better emphasize multiplicity-in-oneness. In each of Yin and Yang, our colors are arranged in "rainbow-order", with the paler/weaker shades bottom-up in Yin, bolder/stronger shades top-down in Yang (exhibiting an appropriate "central-symmetry," not present in other renditions). This has the curious (though completely defensible/justifiable) property of switching the white/black squares from where they would "naturally" "look best" (namely, because yin/yang-like principles dictate that the washed-out/weak/yin square should be put in the bright/strong/yang region, and vice versa for yin). It is preferable to separate the colors in the manner seen here (rather than, say, complete separation of red/hot-like vs. blue/cold-like, or of exact-same colors in both regions, or any other arrangement), better drawing attention to the coequality-with-subtle-distinction/symmetry of Yin and Yang, as opposed to diversity/discrimination/irreconciliation.
