In his book, Concealing Coloration in the Animal Kingdom, Thayer presented his beliefs of protective coloration as an essential factor in evolution helping animals disguise themselves from predators. Thayer, an American artist, devoted much of his life to understanding how animals conceal themselves in nature for survival. In this illustration Thayer shows how a peacock can disappear into its surroundings. American artist Abbott Thayer introduced the concept of disruptive patterning, in which an animal’s uneven markings can disguise its outline. Illustrstions by Abbott Handerson Thayer (his father)Ĭoncealing-Coloration in the Animal KingdomĬan you find the animal hiding in this image? Camouflage uses color to conceal forms by creating optical illusions. Subtractive primary colors - blue, red, and yellow – are often taught to us as children, and when mixed together they create black. Books, paintings, grass and cars are examples of a subtractive color system which is based on the chemical makeup of an object and its reflection of light as a color. Red, green and blue are the primary additive colors and when combined they produce transparent white light. Rainbows, TVs, computer screens and mobile devices all emit light and are examples of an additive color system (the subject of Newton’s Opticks). Le Blon’s distinction marks the first documentation of what is now referred to as additive and subtractive color systems. He makes an important distinction between “material colors,” as used by painters, and colored light, which was the focus of Newton’s color theories. Le Blon was the first to outline a three-color printing method using primary colors (red, yellow, blue) to create secondary colors (green, purple, orange). This very rare book formed the foundation for modern color printing.
