RAL 740-3 vs Iron Ore
RAL 740-3 (RAL Effect) and Iron Ore (Sherwin-Williams) come from different manufacturers. RAL 740-3 reads as green, while Iron Ore reads as grey — two distinct hue families, not close cousins. The 40-point LRV gap — 45 for RAL 740-3 vs 6 for Iron Ore — means RAL 740-3 will open up a space more effectively. A ΔE of 50.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 740-3 vs Iron Ore in Real Spaces
6 real rooms side by side. Seeing RAL 740-3 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. RAL 740-3 reflects noticeably more light off the walls, making the space read more open than Iron Ore.
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. RAL 740-3 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. RAL 740-3 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. RAL 740-3 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. RAL 740-3 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. RAL 740-3 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

RAL 740-3 vs Iron Ore Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 740-3 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.
