Unified Pattern — Pair of two — YIN + YANG, hexagram 8 (Yu, Enthusiasm — King Wen no. 16)
One of 256 distinct Unified Patterns — a 12×12 Jacquard construction where every cell's colour is read off a single hexagram of the Yi King, hexagram Yu, Enthusiasm. Binary numbering 0–63; in brackets, the traditional King Wen number.
Family Pair of two — YIN + YANG, one of the 8 admissible families (out of 15) in the system's classification — see the lexicon for how families are built and admitted.
The pattern's three colour classes, set independently — change one, the other two stay put.
One tint, read in light and dark — a luminance reading, not three colours with two greyed out.
Reading the cell, line by line
The 144 cells of the 12×12 cell fall into six levels of 24 cells, one per line of the hexagram. Where the line is solid (yang), the level takes its colours from the family's YANG grid; where it is broken (yin), from its YANG mutant grid. Count of each colour, level by level:
| Level | Line | Grid read | Colour 1 (violet) | Colour 2 (magenta) | Colour 3 (orange) |
|---|---|---|---|---|---|
| 1 | broken | YANG mutant | 8 | 8 | 8 |
| 2 | broken | YANG mutant | 8 | 8 | 8 |
| 3 | broken | YANG mutant | 8 | 8 | 8 |
| 4 | solid | YANG | 8 | 8 | 8 |
| 5 | broken | YANG mutant | 8 | 8 | 8 |
| 6 | broken | YANG mutant | 8 | 8 | 8 |
| Whole cell | 48 | 48 | 48 | ||
The three colours are exactly balanced: 48 cells each. The cell is unchanged by a quarter turn, a half turn.
Hexagram 8 (King Wen no. 16) — Enthusiasm
Upper trigram ☳ Zhen (The Arousing, Thunder); lower trigram ☷ Kun (The Receptive, the Earth).
Image
Thunder bursts forth from the Earth: the image of enthusiasm. Contained energy suddenly releases, and this eruption sets everything around it into motion — nothing remains still before such a burst. This is the figure of contagious momentum, one that carries others along without needing to force them. Thus the ancient kings honored merit through music and virtue: well-directed enthusiasm becomes the gentlest and most powerful force for gathering wills together.
Judgement — Momentum
Thunder rises from the earth and sets bodies into motion. There exists an energy that cannot be commanded, that springs forth and carries along of its own accord, without needing to be forced. This line teaches that the true power to gather others never comes from constraint, but from that shared vibration which only sincere enthusiasm can awaken.

Same shape, other colourings
Two involutions leave this motif's shape unchanged and only permute its three tints — verified across every family and every hexagram in the corpus, not just this one: swapping the pairing used to read the hexagram (YANG/YANG-mutant ↔ YIN/YIN-mutant), and taking the hexagram's binary complement (63 − 8 = 55). Toggle them below; the tiling never changes, only the colours do.
