Acorn vs Thames Fog
Where Acorn belongs to Benjamin Moore's range, Thames Fog is a Valspar color. Acorn reads as beige-greige, while Thames Fog reads as grey — two distinct hue families, not close cousins. Thames Fog (LRV 27) reflects noticeably more light than Acorn (LRV 21), a difference of 7 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 20.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
