CCE Color Theory & Psychology 3 — Questions and Answers
Question 1: A designer wants to create a split-complementary color scheme starting from violet. Which two hues complete the scheme?
- Yellow-green and yellow-orange (Correct answer)
- Red-orange and blue-green
- Orange and green
- Red and green
Correct answer: Yellow-green and yellow-orange
A split-complementary of violet uses the two hues flanking its complement (yellow): yellow-green and yellow-orange.
Question 2: Which psychological effect describes the phenomenon where red objects appear to advance toward the viewer spatially?
- Chromostereopsis (Correct answer)
- Bezold effect
- Purkinje shift
- Spreading effect
Correct answer: Chromostereopsis
Chromostereopsis is the perceptual illusion where certain wavelengths (especially red) appear closer than others (blue) due to chromatic aberration.
Question 3: In the CIELAB color space, the 'b*' axis represents which color dimension?
- Blue-yellow (Correct answer)
- Red-green
- Lightness
- Chroma
Correct answer: Blue-yellow
In CIELAB, b* runs from blue (negative values) to yellow (positive values), while a* covers red-green.
Question 4: A retailer uses bright yellow signage to draw attention to sale items. Which psychological principle is being applied?
- High luminosity increases visual salience (Correct answer)
- Yellow triggers feelings of trust
- Yellow is a receding color that frames attention
- Warm hues lower arousal for focused reading
Correct answer: High luminosity increases visual salience
Yellow has the highest luminosity among hues and naturally attracts the eye, making it effective for attention-grabbing signage.
Question 5: The Purkinje shift describes a change in color sensitivity that occurs when:
- Moving from photopic (bright) to scotopic (dim) vision (Correct answer)
- Viewing colors under fluorescent versus incandescent light
- Adapting from warm to cool color temperatures
- Transitioning between additive and subtractive color mixing
Correct answer: Moving from photopic (bright) to scotopic (dim) vision
The Purkinje shift is the eye's shift in peak sensitivity from ~555 nm (photopic) toward ~507 nm (scotopic) as light levels drop.
Question 6: Which color scheme uses four hues equally spaced around the color wheel?
- Tetradic (square) (Correct answer)
- Triadic
- Split-complementary
- Analogous
Correct answer: Tetradic (square)
A tetradic or square scheme uses four hues at 90° intervals on the color wheel, offering rich contrast and variety.
Question 7: Research in color psychology consistently shows that blue is associated with which of the following traits in branding?
- Trustworthiness and competence (Correct answer)
- Excitement and urgency
- Playfulness and creativity
- Luxury and exclusivity
Correct answer: Trustworthiness and competence
Blue is the most trusted color in branding research, consistently linked to reliability, competence, and professionalism.
