I really liked this book, and I checked it out from the library but I'm going to buy it. I didn't mind the format or the fact that she spoke about her modern-day expeditions for the colors.
According to the Torah, God told Moses to tell the Israelites to make "fringes on the borders of their garments and put upon the fringe of each corner a thread of blue." The Talmud went farther to specify that the blue had to come from a sea creature that had a shell. The tsitsit shawl and fringe remind Jewish men of their responsibilities. The process to create this blue has been lost and rediscovered, many times over. between 1913 and 1980, all experiments done revealed purple, not blue, and usually involved the wrong sea creature.
Then in 1980 an chemist called Otto Elsner who experimented with woad dyes noticed something extraordinary, that dying on a sunny day came out blue, while on cloudy days it was purple. This however did not solve the problem of how the Ancients made the pigment into a dye. "The Israelites sent him a vial of pigment from Murex trunculus and some wool. He was excited by the opportunity to test his theory that if Tyrian purple contains indigo, then perhaps, like woad and indigo, it needs to have the oxygen removed from the vat before it can become a dye. And what more convenient ingredient for achieving this than the rotting meat of the mollusk (which would cause the bacteria to putrefy and use up the oxygen)?" He added some pickled cockles, which are similar to the murex that had supplied the pigment, after he washed off the vinegar. His solution turned from purple to green, and "the first time he dipped a cloth into the liquor it turned purple. But later he found that if the dissolved greenish liquor was exposed to light, any cloth he put into it turned green and then - in the air - turned blue.
This process has the theological neatness of embracing something holy, born of light. and like the blue thread, was on the fringe of the garment and metaphorically on the fringe of what is allowed in Jewish traditions. The Tyrian blue is one of the least kosher colors; Shellfish are as anathema to Jews as pork.
and then here are some other little tidbits:
*the first artist was a Corinthian woman
*ochre is the oldest color, in all its variations
*pencils were painted yellow to imitate the Chinese Manchu robes
*Joseph Lovibond invented the first system to judge the quality of beer by comparing it against shades of brown stained glass
*after the 18th century, brown ink was made from sepia, the dark liquor secreted by cuttlefish when they are afraid
*Red was originally made from the blood of cochineal bugs, found on cacti
*In the production of red in the 17th century, alum was the agent that gave the dye its teeth. it's rumored that King Henry VIII of England only married Ann of Cleves to get his hands on her alum
*Turkish Miniatures were actually named after the orange that was prevalent
*Saffron is really tricky to harvest. The romantic Spanish do not grow very much and they deal with the mice by smoking them out, while in Iran, they are killed with motorcycle smoke
*Cleopatra used to take a saffron bath before inviting a man to her boudoir
*In China, green porcelain, or mi se, pronounced "mee-ser" was a big secret reserved for the wealthy and holy. it was admired for its unusual and rare beauty. the color would crackle slightly on the surface, making it perfectly imperfect
*Green wallpaper was made with arsenic, and might have led to the premature death of Napolean at St. Helena
*Green cloth was a sign of wealth in Robin Hood's time, so the fact that his garb was green was another example of stealing from the rich to give to the poor
*Cennino's third green was often referred to as van Eyck green because he used it so well, especially in The Arnolfini Marriage. This painting may be an allegory to sexual abuse rather than a celebration of marital bliss
*Blue is made from Lapis Lazuli, which is a rock that contains speckles of iron pyrite, fool's gold, and is mined in Afghanistan
*John Herschel invented the "blueprint" in 1842
*woad was used to make Indigo dye in the time of England's Braveheart, and was used to paint the warriors. it was also an extraordinary astringent, so they were also setting up a primitive field hospital while they were bathing in vats of woad
*it was Newton that added orange and indigo to the spectrum. he decided there would be seven colors, because seven was a divine number. at the time there were only seven known planets, seven days of the week, seven musical notes. The Chinese use the number five; five elements, five tastes, five musical notes, and five colors: black, white, red, yellow and blue
*In Hindu India, blue is often a lucky color, the color of Krishna, the god who dances around the world making both love and fun
*As recently as 1952, Violet (or more like Mauve) was a color of mourning. when King George VI died in '52, "black and mauve knickers were solemnly placed in haberdashers' windows"
*Phoenicians from Lebanon arrived from the Arabian peninsula in the third millennium B.C. Their name derives from the Greed word for Purple, phoinis. They made violet from the shells of mollusks that live along their rocky coast
*Violet is made in Costa Rica by squeezing a shellfish until it barfs up the dye which reacts to air by first being a neon green, then yellow, and finally purple
