Silver Marlin vs Copen Blue
Silver Marlin (Benjamin Moore) and Copen Blue (Sherwin-Williams) come from different manufacturers. Silver Marlin reads as green-grey, while Copen Blue reads as blue-green — two distinct hue families, not close cousins. The 3-point LRV gap — 59 for Copen Blue vs 56 for Silver Marlin — means Copen Blue will open up a space more effectively. Where Silver Marlin leans green, Copen Blue reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 1.6 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Silver Marlin vs Copen Blue in Real Spaces
2 real rooms side by side. Silver Marlin and Copen Blue 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. Copen Blue brings more warmth to the space, while Silver Marlin keeps things cooler and crisper.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Silver Marlin reads more restrained here, while Copen Blue adds a sense of enclosure and warmth.

Silver Marlin vs Copen Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Silver Marlin on one side and Copen Blue 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.
