Cascade Green vs Coastal Plain
Cascade Green and Coastal Plain come from the same Sherwin-Williams collection. Both sit in the green-grey family, which is useful context if you're narrowing within a single hue direction. The 6-point LRV gap — 43 for Cascade Green vs 37 for Coastal Plain — means Cascade Green will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. ΔE 4.3 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cascade Green vs Coastal Plain in Real Spaces
4 real rooms side by side. Cascade Green 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Cascade Green reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Cascade Green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Cascade Green reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Cascade Green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Cascade Green vs Coastal Plain Simulated Comparison
5 simulated room previews — drag the slider on each to see Cascade Green on one side and Coastal Plain on the other.
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.
