Semanticus F. Alpaerts suggests in De Denkbeeldige Ruimte (1980) that the I Ching or Book of Changes, originating from mythical antiquity, is the first semantic lexicon of mankind. In this Chinese classic, unquestionably one of the most influential books in the world’s literature, 64 chapters are coded with a double triplet line code called hexagrams.

Alpaerts used the Wilhelm (1971) translation to show a possible connection between the code lines from the I Ching and the codon encoding in the Semantic Colour Space. The open (- -) and closed (—) lines from the I Ching correspond with respectively the 0’s and 1’s from his semantic coding system. This way he could associate the concepts described in the 64 chapters of the I Ching, with the eight primary colours and their combinations (8×8) from his classification. Later, his hypothesis was confirmed by a comparative research he conducted on the similarities between his keyword-colour classifications, in which the concepts from the I Ching form an important part, and the empirical data from sociologist Eva Heller’s word-to-colour association study (Alpaerts, 1993).

The following list includes I Ching chapter titles with links to pages in the DSD (between brackets: if the title is not in the DSD, a synonym), chapter numbers, digital coding (hexagram), and colour combinations.
