RAL 110-4 vs Fortitude
RAL 110-4 (RAL Effect) and Fortitude (Sherwin-Williams) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 57 vs 56 — so neither will read significantly brighter or darker than the other. A ΔE of 1.1 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
RAL 110-4 vs Fortitude in Real Spaces
1 real room side by side. RAL 110-4 and Fortitude 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.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

RAL 110-4 vs Fortitude Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 110-4 on one side and Fortitude 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.
