Grey Blue vs Iron Ore
Grey Blue (RAL Classic) and Iron Ore (Sherwin-Williams) come from different manufacturers. Their light reflectance values are nearly the same — 7 vs 6 — so neither will read significantly brighter or darker than the other. ΔE 8.8 means they're clearly different, but not dramatically so — they'd pair well in the same room.
Grey Blue vs Iron Ore Color Comparison
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.
Color Details
Grey Blue vs Iron Ore in Real Spaces
Grey Blue and Iron Ore are close enough that the difference can be hard to judge from a chip alone. These real-room photos show how each reads at scale, across different spaces and lighting conditions. Showing 4 room types where both colors have photos.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. The distinction reads clearly at room scale, making the choice between them concrete.
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.
