Module 1: Color Perception


  1. Color perception cannot exist without:
      A. a light source
      B. an illuminated object
      C. a human observer
      D. all of the above

  2. You see more color, contrast and saturation as light increases in:
      A. angularity
      B. intensity
      C. spectral distribution
      D. color temperature

  3. The color spectrum is produced by variation in:
      A. wavelengths of light
      B. brightness
      C. absorption
      D. color gamut

  4. Standardized viewing conditions are recommended for critical color evaluation because:
      A. all "white light" sources have the same spectral distribution
      B. all "white light" sources do not have the same spectral distribution
      C. all human observers are the same
      D. all human observers are not the same

  5. When setting up a color monitor, the color temperature or "white point" you select varies depending on your final output medium. If your work will be produced on a printing press, the recommended white point is:
      A. 5000 K
      B. 6500 K
      C. 2800 K
      D. 9300 K

  6. When light strikes an object, it may be:
      A. reflected
      B. transmitted
      C. absorbed
      D. all of the above

  7. When you use a densitometer, you are measuring the:
      A. spectral distribution of light
      B. color temperature
      C. amount of light reflected or transmitted
      D. amount of color saturation

  8. If you have normal vision, you are an excellent judge of very slight shifts in color when two samples are viewed:
      A. with a different light source for each sample
      B. with a different color field surrounding each sample
      C. one after the other
      D. side-by-side

  9. Differences in the spectral distribution of skylight and household tungsten lights change the appearance of objects. Yet your eye adjusts to these overall color shifts automatically through a process called:
      A. chromatic aberration
      B. chromatic adaptation
      C. color contrast control
      D. color vision deficiency

  10. Color can be defined by three properties. Which is not among them?
      A. brightness (lightness)
      B. hue
      C. contrast
      D. saturation

  11. When you say "This object is green, that one is red," you are referring to differences in which property?
      A. brightness (lightness)
      B. hue
      C. contrast
      D. saturation

  12. When you see a color wheel on your computer monitor, one of the three dimensions of color is missing. Which one?
      A. brightness (lightness)
      B. hue
      C. contrast
      D. saturation

  13. All the following statements about CIE color values are true except one. Which one is false?
      A. They are based on colorants used to produce color.
      B. They provide a foundation for scientific color measurement and color management software.
      C. They allow us to compare color gamuts of different systems.
      D. They are based on human perception of color.

  14. Unlike a colorimeter, a spectrophotometer is an instrument that measures:
      A. density
      B. CIE color values
      C. wavelengths at many points throughout the spectrum
      D. color temperature

  15. Which of these familiar imaging systems has the smallest color gamut?
      A. digital color printers
      B. transparency films
      C. conventional printing presses
      D. color monitors
