CAP CAP Color Theory and Lighting 1 — Questions and Answers
Question 1: In animation, what term describes the perceived brightness or darkness of a color independent of its hue?
- Saturation
- Value (Correct answer)
- Chroma
- Temperature
Correct answer: Value
Value refers to the lightness or darkness of a color and is a core element of the HSV color model used in animation.
Question 2: Which color harmony places two colors directly opposite each other on the color wheel?
- Analogous
- Triadic
- Complementary (Correct answer)
- Split-complementary
Correct answer: Complementary
Complementary colors sit 180 degrees apart on the color wheel and create maximum contrast when placed side by side.
Question 3: In 3-point lighting for animation, what is the purpose of the fill light?
- Cast dramatic shadows on the subject
- Illuminate the background separately
- Soften shadows created by the key light (Correct answer)
- Create a rim around the subject's silhouette
Correct answer: Soften shadows created by the key light
The fill light reduces the harshness of shadows produced by the key light, controlling the overall contrast of the scene.
Question 4: What color temperature (in Kelvin) is typically associated with warm, golden-hour sunlight in animation lighting?
- 6500K
- 5500K
- 3200K (Correct answer)
- 10000K
Correct answer: 3200K
Warm golden-hour light is around 3200K, producing an orange-yellow tone used to suggest sunrise or sunset scenes.
Question 5: Which rendering technique simulates how light bounces between surfaces to produce realistic ambient lighting in 3D animation?
- Ray casting
- Global illumination (Correct answer)
- Ambient occlusion
- Phong shading
Correct answer: Global illumination
Global illumination calculates indirect light bouncing off surfaces, producing soft, realistic ambient lighting throughout a scene.
Question 6: In color grading an animated film, what does 'lifting the blacks' typically do to the image?
- Increases contrast in shadow areas
- Adds a faded, cinematic look by raising shadow brightness (Correct answer)
- Saturates dark colors
- Converts the image to HDR
Correct answer: Adds a faded, cinematic look by raising shadow brightness
Lifting the blacks raises the minimum luminance value of shadows, producing a faded look common in cinematic color grades.
