Color Theory

  1. 1. What is Color?
  2. 2. Color is the visual perception by the human eye of the light spectrum. Because perception of color stems from the varying sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells.
  3. 3. <ul><li>After light enters the retina , color processing after that point is organized differently. Scientists think that color information is transmitted out of the eye by three channels, each constructed from the output of the cones : a red - green channel, a blue - yellow channel and a black - white channel. This theory has been supported by various tests, and accounts for the human brain predicting the color wheel! </li></ul>
  4. 4. <ul><li>If one or more types of a person's color-sensing cones are missing or less responsive than normal to incoming light, that person can distinguish fewer colors and is said to be color deficient or color blind . Some kinds of color deficiency are caused by anomalies in the number or nature of cones in the retina. Others have anomalies in those parts of the brain where visual processing takes place. </li></ul>
  5. 5. Where does color come from? <ul><li>Color comes from natural or artificial light and can change depending on many factors. Where there is little light, there is little color. With bright light, colors are more intense! </li></ul><ul><li>When a ray of white light passes through a prism, it breaks into individual bands of color called the color spectrum . </li></ul>
  6. 6. <ul><li>This picture of the electromagnetic spectrum shows several wavelength regions, for example X rays, visible light, and microwaves. The light that our eyes are sensitive to lie in a very small region of the electromagnetic spectrum labeled visible light corresponding to a wavelength range of 400 - 700 nanometers and a color range of violet through red . So if someone says that a photon is &quot;redder&quot; than another, they mean it has a longer wavelength. Similarly, a &quot;bluer&quot; photon would have a shorter wavelength. </li></ul>
  7. 7. How do artists use color? <ul><li>Artists use pigments , which are colored powdered substances that are natural or chemically based. Pigments are combined with other substances to make the various paints, crayons, inks and pencils we use in our everyday lives! </li></ul>
  8. 8. <ul><li>Not all objects have colors that are in the spectrum. Stars in the night sky appear white. Smoke may be gray. Ink is often black. Because we do not see any one color in them, white, gray and black are called neutrals . </li></ul><ul><li>White = The sum of all colors </li></ul><ul><li>Gray = Part of all the wavelengths </li></ul><ul><li>Black = The total absence of reflected light </li></ul>
  9. 9. The Basics <ul><li>Primary Colors- Red , Yellow , Blue </li></ul><ul><li>Secondary Colors- Orange , Green , Violet </li></ul><ul><li>Hue- The name of a color itself. </li></ul>

  11. 11. Color Mixing <ul><li>Tint = A color + white </li></ul><ul><li>Shade = A color + black </li></ul><ul><li>Tone = A color + gray </li></ul>
  12. 12. color symbolism <ul><li>Successful design requires an awareness of how and why colors communicate meaning. The source of these meanings can be quite conspicuous, such as those found in nature — red is the color of blazing fire and blood , blue the color of cooling waters and the sky . Other meanings may be more complex and not universal. </li></ul><ul><li>Green’s associations with nature communicate growth, fruitfulness, freshness and ecology. On the other hand, green may also be symbolic of good luck, seasickness, money and greed — all of which have nothing to do with green plants. </li></ul>
  13. 13. <ul><li>Furthermore, color may have both positive and negative symbolism. For example, although blue is the beautiful color of the sky on a sunny day, it can be symbolic of sadness or stability. These traits are seen in phrases such as “singing the blues” and “blue chip stocks.” </li></ul><ul><li>Red is another example of dual symbolism. On one hand, as the color of fire and blood, it is an energizing, aggressive and bold color. In direct contrast, red is used for “ STOP ” signs throughout the world today. </li></ul>
  14. 14. Sources for symbolism <ul><li>Cultural associations : the color of currency, traditions, celebrations and geography. </li></ul><ul><li>Political and historical associations: the color of flags, political parties and royalty. </li></ul><ul><li>Religious and mythical associations: the colors associated with spiritual or magical beliefs. </li></ul><ul><li>Linguistic associations: color terminology within individual languages. </li></ul><ul><li>Contemporary usage and fads: current color applications to objects, sports, and associations generated by modern conventions and trends. </li></ul>
  15. 15. Color & emotion <ul><li>Red is the first primary color of the spectrum. It emotionally triggers the sense of power, impulsively and increases one's appetite. Be careful how you use red! It can also shout anger, forcefulness, impatience, intimidation, conquest, and violence. </li></ul>
  16. 16. <ul><li>Orange is a secondary color comprised of the primary colors, yellow and red. It emotionally triggers steadfastness, courage, confidence, friendliness, and cheerfulness. Its opposite effects are ignorance, inferiority, sluggishness and superiority. Orange is generally considered a social color but used in the wrong manner and with the wrong color combinations could create the opposite effects listed. </li></ul>
  17. 17. <ul><li>Yellow is one of the three primary colors. Visually it is the most difficult for your eyes to focus on. It is actually brighter than white and stronger in its emotional impact. It also has a stimulating impact on your memory! (Yellow notepads and Post-It Notes?) It triggers intelligence, joy, and organization. Its opposite effects when used in the wrong manner or with the wrong combination of other colors can create feelings of criticism, laziness, or cynicism. </li></ul>
  18. 18. <ul><li>Green is the combination of two primary colors, yellow and blue. It includes all the qualities of yellow and blue and the emotions it triggers depends on which of the two primary colors is dominate. Green triggers the following positive emotions: hope, growth, good health, freshness, soothing, sharing, and responsiveness. Its negative attributes are envy, greed, constriction, guilt, jealousy and disorder. </li></ul>
  19. 19. <ul><li>Blue is a primary color. It is the easiest color for the eyes to focus. It generates feelings of tranquility, love, acceptance, patience, understanding and cooperation. Its negative qualities if used inappropriately are fear, coldness, passivity and depression. Blue is a favorite color choice among all age groups. </li></ul>
  20. 20. <ul><li>Violet is a secondary color that signifies deep passion, wealth and nobility. It suggests sophistication, intelligence, dignity and spirituality. This luxurious color also symbolizes power and stability. Violet is associated with wisdom, dignity, independence, creativity, ambition and mystery. </li></ul>
