Sharkskin vs Gateway Gray in Real Spaces
2 real rooms side by side. Sharkskin and Gateway Gray are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
