Big Fish vs Coastal Plain in Real Spaces
4 real rooms side by side. Big Fish and Coastal Plain 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.

Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Bathroom

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
