One Straw-Yellow Color

On the shroud, the images are halftone straw-yellow and white, meaning the shade of straw-yellow from its darkest parts to it lightest parts are made up of bits of one straw-yellow color. The term pixel has often been used to describe this. It’s a wonderful word but it is a confusing word, just like the word salt. You add salt to soup to enhance the flavor. But when the cook hasn’t added enough salt you say to someone, “Please pass the salt.” You should say, if you want to be precise, “Please pass the sodium chloride.” You certainly wouldn’t want to sprinkle too much magnesium sulfate commonly known as Epsom salt on your food unless you want a very effective laxative.  And you certainly wouldn’t want to sprinkle lead diacetate on your food to make it taste saltier, for it tastes sweet. You also wouldn’t use it anyways because it leads to slow and certain lead poisoning. For centuries, before anyone knew better, lead sugar, as it was sometimes called, though it is really a salt, was used as an artificial sweetener.
