Color and value
- 1. Color and Value relationship Sumit Chaudhary 11737
- 2. Essentials Light is made of all colors (Sir Isaac Newton put white light through a prism = colors) Color is a property of light. Objects have no color of their own, they just reflect a particular wavelength from the color spectrum. (For example a blue object absorbs all of the wavelengths, EXCEPT the blue ones, thus the blue ones are reflected back to our eyes). Black absorbs all the wave lengths of the color spectrum. White reflects all the wave lengths of the color spectrum.
- 3. Color Wheel The most common organization for the relationship of the basic colors is the color wheel. (Wheel system dates from the 18th century.) • 3 Primary Colors : Red, Yellow and Blue • 3 Secondary Colors : mixtures of the primary colors. Orange, Green and Violet • 6 Tertiary Colors - mixtures of a primary and a secondary color.
- 4. Color Interaction Colors change with their context. Amounts and repetition are also critical factors. Here green looks different “woven” through black or white.
- 5. Color Discord and Vibrating Colors Unexpected Combinations Color Discord – the opposite of color harmony. Can be visually disturbing. They do not balance each other nor do they have affinity for each other. Mild discord can be exciting or stimulating.
- 6. Planning Color Schemes lnteriors, posters, and packaging are the most common deliberate use of color schemes….other areas may be more intuitive. Knowing these harmonies can help all artists and designers consciously plan the visual effects they want a finished work to have.
- 7. Properties of Color: Value Value - Lightness or darkness of the hue Tint - adding white to a hue = high value color Shade - adding black to a hue = low value color Most people can distinguish at least 40 tints and shades of any color Value scales for blue, gray, and yellow with equal visual steps.
- 8. Changing Color Value When working with paint you can thin a color by adding medium. The more transparent a color is, the lighter it’s value placed over white. You can also alter the value by mixing hues together. Value, just like color, is changed by its surroundings.
