Q
  • Is high in yellow
  • Is favorable to most cosmetic colors
  • When compared to flourescent light, the white bulb is better for highlighting:
    • Fabric Textures
    • Wood-grains on caskets
  • Lamps with this light have a downward thrust lacking in fluorescent lamps.
A

16
Q
  • Red, Green, Blue
  • Correct mixture of these primary hues can form every other hue.
A

Primary Hues of The Additive Method

17
Q
  • Yellow, Blue-Green (cyan), Magenta
  • Are made by projection of equal strengths of pairs of primary hues.
A

Secondary Hues- Additive Method

18
Q

Secondary hues of the additive method are the _____ hues of the subtractive method.

A

Primary

19
Q

Equal Mixtures of these in the additive method produce white.

A

Complements

20
Q

Involves the diminution (subtraction) of the wave lengths of light.

  • Reduction can gradually extend to a point where a complete black-out results.
A

Subtractive Method

21
Q

Absence of any illumination.

A

Black-Out

22
Q

One light source with two or more filters.

A

Application of The Subtractive Method

23
Q
  • Yellow
  • Blue-Green (Cyan)
  • Magenta
  • These are the secondary hues of the additive method.
A

Primary Hues of the Subtractive Method

24
Q
  • Emphasis
  • Absorption
  • Conversion
A

Effect of Colored Lights on Colored Objects

25
Q

The hue of an object appears more vivid when seen under the same hue of illumination.

A

Emphasis

26
Q

When two values or intensities of the same hue are present (and the same hue in illumination strikes them) the larger area appears more vivid while the smaller, more “washed-out.”

A

Absorption

27
Q

If the hue of an object and the illumination differ, the color of the object with either be converted into a different color or be obliterated.

A

Conversion

28
Q
  • Green + Blue Light = Cyan
  • Red + Blue light = Magenta
  • Green + Red light = Yellow
A

Additive Color System

29
Q

Cyan + Magenta + Yellow = Black

A

Subtractive Color System

30
Q

In the subtractive color system, this absorbs red light, reflects green and blue light.

A

Cyan

31
Q

Absorbs green light, reflects red and blue light.

A

Magenta

32
Q

Absorbs blue light, reflects red and green light.

A

Yellow

33
Q

Absorbs green and blue light, reflects red light, appears red.

A

Magenta + Yellow

34
Q

Absorbs red and blue light, reflects green light, appears green.

A

Cyan + Yellow

35
Q

Absorbs red and green light, reflects blue light, appears blue.

A

Cyan + Magenta
