Which practice helps ensure color consistency across wall coverings?

• A. Dye lots, sequential rolls, batch numbers, and material imperfections
• B. Brand name is sufficient
• C. Texture is the only concern
• D. Only the overall color appearance matters.

Answer: (C)

Color appearance on finished walls is driven by how the surface texture interacts with light. Even with the same pigment, smooth, flat areas will reflect light differently than textured or embossed ones, causing the color to look lighter, darker, or slightly off in different spots. To keep color consistent across wall coverings, you need to match the texture characteristics across all surfaces—same embossing, same level of roughness, and similar sheen—so light behaves the same way everywhere. While controlling dye lots and batch numbers helps with manufacturing consistency, the way texture affects perception is the main factor in achieving uniform color in the room.
