Gem Silica vs Arsenic
Where Gem Silica belongs to Behr's range, Arsenic is a Farrow & Ball color. Both sit in the green family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (39 vs 37), so they'll read as similarly Medium in most lighting conditions. Gem Silica runs green while Arsenic is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 11.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gem Silica vs Arsenic in Real Spaces
4 real rooms side by side. Seeing Gem Silica and Arsenic in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. The distinction reads clearly at room scale, making the choice between them concrete.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

5 simulated room previews — drag the slider on each to see Gem Silica on one side and Arsenic 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.
