Blue Echo vs S 4010-B70G
Blue Echo (Benjamin Moore) and S 4010-B70G (NCS) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 3-point LRV gap — 28 for S 4010-B70G vs 24 for Blue Echo — means S 4010-B70G will open up a space more effectively. Where Blue Echo leans blue, S 4010-B70G reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 6.6 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Blue Echo vs S 4010-B70G in Real Spaces
1 real room side by side. Blue Echo and S 4010-B70G 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. S 4010-B70G reads slightly lighter here — a subtle but real difference in how open the space feels.

5 simulated room previews — drag the slider on each to see Blue Echo on one side and S 4010-B70G 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.
