How does increasing the gun movement speed affect color?

• A. lightens
• B. darkens
• C. no change
• D. unpredictable

Answer: (A)

When color depth depends on how much pigment is deposited, the film thickness of the color layer matters. Spraying the gun faster reduces the amount of paint that lands on the surface in each pass, so you build a thinner pigment film. With a thinner film, there’s less pigment per area, which makes the color appear lighter. If you need a deeper, more saturated color, you’d typically spray more slowly or make more passes to build up pigment and thickness. Quick movement can also lead to uneven coverage, but the core idea is that faster motion = thinner film = lighter color.
