Color Theory & Application Flashcards

When a vehicle has significant paint fade due to sun exposure, what challenge does this create for an adjuster approving a color match?

Answer: The repaired panel may appear noticeably newer and brighter than surrounding faded panels, making blending critical

Sun-faded panels have lost pigment depth and sheen, so new paint on a repaired panel will appear brighter unless surrounding panels are blended or corrected.

Oxidation of an older vehicle's paint finish most commonly presents as which visual condition?

Answer: A chalky, dull, or cloudy surface appearance with loss of sheen

Oxidation degrades the paint binder through UV exposure, leaving a chalky, dull surface as the top layer breaks down and loses its ability to reflect light.

What is the correct term for the distance of coverage around a damage area that a painter fades new paint into to hide the repair?

Answer: Blend area

The blend area is the surrounding region where new paint is tapered into existing paint to create an imperceptible transition between repaired and unrepaired surfaces.

Under most CA-licensed adjuster standards, who is responsible for verifying that a color match is acceptable before returning a vehicle to the owner?

Answer: The repairer, with the vehicle owner's final approval upon delivery

Best practice and most industry standards place final color match acceptance with the repairer performing quality control and the vehicle owner confirming satisfaction at delivery.

A custom-mixed color formula that is slightly 'too blue' compared to the vehicle can be corrected by adding which type of pigment?

Answer: An opposing warm color (orange or yellow) to neutralize the excess blue

Color theory holds that opposing (complementary) colors cancel each other out, so adding a warm complement neutralizes an excess cool (blue) tone in a paint mix.

What does 'strike-in' refer to in automotive refinishing?

Answer: The absorption of base coat solvents into a soft or unseal primer, causing color darkening or mottle

Strike-in occurs when the solvent in a base coat is absorbed by an unsealed or soft substrate, altering the color value and causing uneven, mottled appearance.

Why might an adjuster request a 'panel blend' on a door adjacent to a repaired quarter panel even if the door itself is undamaged?

Answer: To ensure the new repair paint transitions invisibly into the undamaged adjacent panel, preventing a visible color line

Blending the adjacent door prevents a visible color demarcation line between the freshly painted quarter panel and the existing door finish.
