Arsenic vs Grey Blue
Arsenic (Farrow & Ball) and Grey Blue (RAL Classic) come from different manufacturers. Arsenic reads as green, while Grey Blue reads as blue-grey — two distinct hue families, not close cousins. The 30-point LRV gap — 37 for Arsenic vs 7 for Grey Blue — means Arsenic will open up a space more effectively. A ΔE of 45.6 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Arsenic vs Grey Blue in Real Spaces
2 real rooms side by side. Seeing Arsenic and Grey Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Arsenic returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Arsenic returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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