CSA Color Theory & Airbrush Techniques 2 — Questions and Answers
Question 1: What color scheme term describes colors that are adjacent to each other on the color wheel, creating a harmonious, low-contrast combination?
- Complementary
- Analogous (Correct answer)
- Triadic
- Split-complementary
Correct answer: Analogous
Analogous colors sit next to each other on the color wheel (such as red, red-orange, and orange) and naturally harmonize because they share underlying hue similarities.
Question 2: What is the correct airbrush technique for creating a smooth ombre or gradient effect on a cake?
- Apply one color then wipe half away before it dries
- Layer successive colors overlapping and blending at the transition zone (Correct answer)
- Use two airbrushes at the same time from opposite directions
- Apply different color stencils side by side
Correct answer: Layer successive colors overlapping and blending at the transition zone
An ombre effect is built by sequentially spraying colors and overlapping them at transition points, gradually fading each hue into the next across the cake surface.
Question 3: What PSI (pounds per square inch) range is generally recommended when airbrushing on fondant-covered cakes?
- 1–5 PSI
- 15–30 PSI (Correct answer)
- 50–70 PSI
- 80–100 PSI
Correct answer: 15–30 PSI
A range of 15–30 PSI provides sufficient pressure for proper color atomization and smooth application without over-saturating fondant or damaging its surface texture.
Question 4: Which airbrush feed system allows for the quickest color changes during a decorating session?
- Gravity-feed (Correct answer)
- Siphon-feed
- Side-feed
- Pressure-feed
Correct answer: Gravity-feed
Gravity-feed airbrushes have a small, easily removable top cup that can be quickly emptied, rinsed, and refilled with a new color, minimizing downtime between color changes.
Question 5: Which technique produces a deliberate 'spatter' or splatter texture when airbrushing on a cake?
- Increasing air pressure while reducing paint flow
- Reducing air pressure while increasing paint flow (Correct answer)
- Holding the airbrush completely stationary at close range
- Using highly diluted, thin airbrush color
Correct answer: Reducing air pressure while increasing paint flow
Reducing air pressure relative to paint flow prevents full atomization, causing the color to release as droplets rather than a fine mist, creating a spatter texture.
Question 6: What is the key practical difference between transparent and opaque food coloring when used with an airbrush on cake?
- Transparent dries faster; opaque takes much longer to dry
- Transparent lets the base color show through; opaque fully covers the base color (Correct answer)
- Transparent is much thicker and requires thinning; opaque flows freely
- Transparent requires higher PSI to spray; opaque works at lower pressure
Correct answer: Transparent lets the base color show through; opaque fully covers the base color
Transparent airbrush colors act as tinted glazes that allow the underlying fondant or base color to remain visible, while opaque colors provide full coverage that conceals the base.
Question 7: What is the correct procedure for cleaning an airbrush between color changes to prevent color contamination?
- Wipe the exterior nozzle with a dry paper towel
- Spray clean water or a food-safe cleaning solution through the mechanism until it runs clear (Correct answer)
- Disassemble and soak all parts in warm water overnight
- Replace the needle and nozzle assembly after each new color
Correct answer: Spray clean water or a food-safe cleaning solution through the mechanism until it runs clear
Flushing the airbrush by spraying clean water or food-safe cleaner through the color path until no residual color remains is the standard in-session cleaning method that effectively prevents contamination.
