Kabbalah su Isaia 34:78

In addition to the above, this metaphor of the four colors includes a particularly important allusion. For the supernal lights are called sefer, book, as it is written (Sefer Yetzira, Chapter 1, Mishna 1): “He created His world with three books: With a book, an author, and a story.”⁷The Hebrew word for “book” is sefer. The literary structure of this line quoted from Sefer Yetzira is that God created His world with three elements (book, author, story) that are different permutations of the word sefer in Hebrew. In addition to sefer (book), an author is a sofer, and a story is a sippur (the letters “p” and “f” are different sounds of the same letter, “peh” in the Hebrew language, so sippur is also a permutation of the word sefer). Thus, using different vowelizations, the same root "sefer" refers to these three elements. It is also written: “The heavens shall be rolled together as a book” (Isaiah 34:4).⁸“Rolled together as a book” here refers to the kinds of books used at the time of the prophecy, namely scrolls, which are rolled up. Now, the manifestation of the wisdom in each book is not in the white background of the pages it contains, but only in the colors, i.e., the ink, from which the letters in the book, through the combinations of letters according to the wisdom, come to the reader. In general, there are three kinds of ink in a book: Red, green, and black.
