RAL 740-5 vs Iron Ore
RAL 740-5 (RAL Effect) and Iron Ore (Sherwin-Williams) come from different manufacturers. RAL 740-5 reads as blue, while Iron Ore reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 7 vs 6 — so neither will read significantly brighter or darker than the other. A ΔE of 34.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 740-5 vs Iron Ore in Real Spaces
3 real rooms side by side. Seeing RAL 740-5 and Iron Ore 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

RAL 740-5 vs Iron Ore Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 740-5 on one side and Iron Ore 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.
