✍️ Sample CBD Questions & Answers
1. Which principle explains why a red towel bar will appear more vivid when mounted against a green tile wall?
Red and green are complementary colors positioned opposite each other on the color wheel, and complementary contrast makes each color appear more saturated and vibrant.
2. Which color has the highest visible light reflectance and would most effectively brighten a dark bathroom?
Pure or near-pure white has the highest LRV (closest to 100), reflecting the maximum amount of visible light and creating the brightest possible environment.
3. What is the term for colors that appear to advance visually toward the viewer in a room?
Advancing colors, typically warm hues like reds, oranges, and yellows, appear to move toward the viewer, making spaces feel smaller and more intimate.
4. In BIM software such as Revit, what does a 'family' refer to?
In Revit, a family is a parametric building component (e.g., fixture, cabinet) whose dimensions and properties can be modified.
5. What is the main advantage of a wall-mounted toilet?
The main advantage of a wall-mounted toilet is that it saves space and allows for easier cleaning. By concealing the tank within the wall, it creates a more open and minimalist aesthetic, which is ideal for smaller bathrooms. The elevated bowl also makes it much simpler to clean the floor underneath, improving overall hygiene.
6. A designer wants to create a triadic color scheme anchored in blue-green. Which two additional colors complete the triad?
A triadic scheme uses three colors equally spaced on the 12-part color wheel — blue-green's triads are red-orange and yellow-orange.
