Blue Spruce vs Britannia Blue
Both are Benjamin Moore colors. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 17 and 18, they'll behave almost identically in terms of how much light they reflect back into a room. They share a blue quality — useful to know if you're layering them in the same space. With a ΔE of 2.5, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Spruce vs Britannia Blue in Real Spaces
2 real rooms side by side. Blue Spruce and Britannia 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.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
House
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.

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