Borrowed Light vs Mountain Air
Where Borrowed Light belongs to Farrow & Ball's range, Mountain Air is a Sherwin-Williams color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Mountain Air (LRV 73) reflects noticeably more light than Borrowed Light (LRV 69), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.

Borrowed Light vs Mountain Air in Real Spaces
1 real room side by side. Borrowed Light and Mountain Air 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
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Mountain Air has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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.
