Color+vocabulary

=__Color__: Effect produced on the eye and its associated nerves by light waves of different wavelength or frequency. Light transmitted from an object to the eye stimulates the different color cones of the retina, thus making possible perception of various colors in the object.= =__Primary Colors__: It's also important to understand the concept of "primary" colors. The fundamental rule is that there are three colors that cannot be made by mixing other colors together. These three, red, blue, and yellow, are known as the primary colors.= = = =__White__: Is a color. White reflects all the colors of the visible light spectrum to the eyes.= = = =__Black__: Is not a color; a black object absorbs all the colors of the visible spectrum and reflects none of them to the eyes. = = = =__The Visible Spectrum__: Since the colors that compose sunlight or white light have different wavelengths, the speed at which they travel through a medium such as glass differs; red light, having the longest wavelength, travels more rapidly through glass than blue light, which has a shorter wavelength. Therefore, when white light passes through a glass prism, it is separated into a band of colors called a spectrum. The colors of the visible spectrum, called the elementary colors, are red, orange, yellow, green, blue, indigo, and violet (in that order). = = = = __Value__: The lightness or darkness of a color is called its **value.** You can find the values of a color by making its tints and shades. = = = = __Tints__: are light values that are made by mixing a color with white. For example, pink is a tint of red, and light blue is a tint of blue.= =**__Shades__**: are dark values that are made by mixing a color with black. Maroon is a shade of red, and navy is a shade of blue.= =Sad: to feel blue.= =Not true but harmless: white lie= =Owe money: be in the red= =Honors: Red carpet.= =By surprise: out of blue= =Complicated offcial procedures: red tape= =Easy to undestand: In black and white= =Having money: in the black= =OK to start something: the green light= =Be jealous: Green with envy= =The market not controlled by the government: The black market=
