Boreal vs Thames Fog
Where Boreal belongs to Behr's range, Thames Fog is a Valspar color. Boreal reads as green-grey, while Thames Fog reads as grey — two distinct hue families, not close cousins. Thames Fog (LRV 27) reflects noticeably more light than Boreal (LRV 19), a difference of 8 points that becomes especially apparent in rooms with limited natural light. The ΔE 9.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Boreal vs Thames Fog in Real Spaces
1 real room side by side. Boreal and Thames Fog 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. Thames Fog returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
