CAP CAP Color Theory and Lighting 2 — Questions and Answers
Question 1: What is the term for a color palette that uses only variations in lightness and saturation of a single hue?
- Triadic
- Monochromatic (Correct answer)
- Analogous
- Tetradic
Correct answer: Monochromatic
A monochromatic palette restricts all colors to shades, tints, and tones of a single hue, creating visual cohesion.
Question 2: In animation lighting, a 'rim light' or 'back light' is primarily used to:
- Illuminate the face from the front
- Separate the character from the background (Correct answer)
- Simulate ambient environment lighting
- Create colored shadows
Correct answer: Separate the character from the background
A rim light placed behind the subject outlines its silhouette, visually separating it from the background.
Question 3: Which term describes the phenomenon where colors appear to shift based on surrounding colors, a key consideration in animation palette design?
- Chromatic aberration
- Simultaneous contrast (Correct answer)
- Gamut mapping
- Color constancy
Correct answer: Simultaneous contrast
Simultaneous contrast means a color's perceived hue and value change depending on the colors surrounding it.
Question 4: What color space is most commonly used as the standard display space for web and broadcast animated content?
- Adobe RGB
- ProPhoto RGB
- sRGB (Correct answer)
- DCI-P3
Correct answer: sRGB
sRGB is the standard color space for web and broadcast, ensuring consistent color display across consumer screens.
Question 5: In lighting for animation, what does the term 'falloff' refer to?
- The angle of the key light
- The rate at which light intensity decreases with distance (Correct answer)
- The color shift of a light over time
- The number of shadow-casting lights in a scene
Correct answer: The rate at which light intensity decreases with distance
Falloff describes how quickly a light source loses intensity as distance from it increases, following the inverse square law.
Question 6: Which of the following best describes 'ambient occlusion' in 3D animation rendering?
- A technique for simulating full global illumination
- A shading method that darkens areas where surfaces meet or are occluded from ambient light (Correct answer)
- A post-process filter for bloom effects
- A color correction applied to shadow regions
Correct answer: A shading method that darkens areas where surfaces meet or are occluded from ambient light
Ambient occlusion darkens crevices and contact points where ambient light is blocked, adding depth and realism cheaply.
