Brush Blue vs Oslo
Where Brush Blue belongs to Benjamin Moore's range, Oslo is a Jotun color. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (10 vs 11), so they'll read as similarly Dark in most lighting conditions. Brush Blue runs blue while Oslo is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Brush Blue vs Oslo in Real Spaces
2 real rooms side by side. Brush Blue and Oslo 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.

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