Sunlight effects on Color
Color is light. Light is a form of energy and, according to theory, travels in waves. Sir Isaac Newton discovered this in 1666 by passing a beam of light through a prism. The renowned English scientist was 23 years old at the time. He was made to stay home from Cambridge University for over a year because the plague that was sweeping Europe had closed it down. It was during this period that Newton performed his famous spectrum experiments. To alleviate the boredom of quarantine, he punched holes in the curtains of his darkened room to study the effects of light passing through a prism. The light separated into the same progression of colors found in the natural rainbow. Although he found an infinite number of colors in this spectrum, Newton wanted to show that there were just seven main colors. He identified red, orange, yellow, green, blue, indigo and violet. This was also in keeping with Aristotle's seven classes of color, which he thought were all mixes of black and white (What is). There are three Primary colors, red, blue and yellow. If you mix two primary colors together, a secondary color is produced. The primary colors are the base of all secondary colors. Red
Colors usually fade in sunlight. The color of the object depends upon their chemical makeup. Objects absorb some colors and reflect others. Some things, such as the ultraviolet rays in sun, can break the chemical bonds. This changes what is reflected back--when the object is bleached white, it reflects all the colors of light. Some objects fade faster simply because their chemical bonds break down faster. By mixing together various amounts of red, green and blue, you can make almost any color. Television screens and computer monitors make their colors by mixing red, green and blue lights. A monitor or television screen mixes a color by illuminating tiny dots of red, green and blue phosphors with an electron gun located at the back of the monitor. By illuminating each of the dots to a different brightness, the monitor creates different colors (Color). Secondary colors are the colors you get when mixing two primary colors together in equal amounts. Orange, green, and violet are secondary colors. The colors are made by mixing equal amounts of primary colors together to produce a different color or shade. Each secondary color is made from the two primary colors (Color Theory). Ultraviolet photons are produced whenever something is heated to a high enough temperature. This can be hydrogen on the surface of the sun or a bright light bulb. Photons travel through space. Photons from the sun must pass through the earth's atmosphere before they can have any effect on us. This is a hazardous step for
