CID CID Color Theory and Application 2 — Questions and Answers
Question 1: What term describes the simultaneous contrast effect where a neutral gray appears to take on the complementary hue of a surrounding color?
- Afterimage
- Color constancy
- Simultaneous contrast (Correct answer)
- Metamerism
Correct answer: Simultaneous contrast
Simultaneous contrast is an optical phenomenon where adjacent colors influence each other's perceived hue, saturation, and brightness.
Question 2: Which Pantone system is most commonly used by US interior designers when specifying paint and textile colors?
- Pantone CMYK
- Pantone Fashion, Home + Interiors (FHI) (Correct answer)
- Pantone Graphics
- Pantone Neon
Correct answer: Pantone Fashion, Home + Interiors (FHI)
The Pantone Fashion, Home + Interiors (FHI) system is specifically developed for soft goods, hard goods, and interior materials specification.
Question 3: What is metamerism in the context of interior color specification?
- The tendency of colors to fade in sunlight
- The phenomenon where two colors match under one light but differ under another (Correct answer)
- The mixing of adjacent colors to create optical blends
- The use of multiple materials in the same color family
Correct answer: The phenomenon where two colors match under one light but differ under another
Metamerism occurs when two color samples appear identical under one light source but differ under a different light source due to different spectral compositions.
Question 4: Which color temperature of artificial light will most accurately show the true color of warm-toned fabrics and finishes?
- 6500K daylight
- 5000K cool white
- 4000K neutral white
- 2700K warm white (Correct answer)
Correct answer: 2700K warm white
A 2700K warm white light source closely mimics incandescent light, accurately rendering warm-toned materials like wood, beige, and earth tones.
Question 5: In color psychology, which color is commonly associated with creativity, energy, and enthusiasm in US commercial interiors such as advertising agencies?
- Blue
- Green
- Orange (Correct answer)
- Purple
Correct answer: Orange
Orange is psychologically associated with enthusiasm, creativity, and warmth, making it popular in creative workspaces and hospitality environments.
Question 6: What does LRV (Light Reflectance Value) measure and why is it important in interior design?
- How fast paint dries on different surfaces
- The percentage of light a paint color reflects, affecting perceived brightness (Correct answer)
- The UV resistance of a finish
- The coverage rate of a paint in square feet per gallon
Correct answer: The percentage of light a paint color reflects, affecting perceived brightness
LRV measures the percentage of visible light reflected by a paint color on a scale of 0–100, influencing how bright or dark a space appears.
