Iron Ore tends to look like a soft black (and at some angles, almost a true black) when paired with pure white trim and light wood finishes.
In a room with a warm color palette, you’ll clearly see that it’s a gray. Most of the time, it looks like a true dark gray, and sometimes the pigmentation looks downright creamy.
LRV = Light Reflectance Value: Rated 0-100 with 0 being pure black, and 100 being pure white.
Sherwin Williams Tricorn Black is dark enough to be considered a true black. It has an LRV of 3, so it’s just a few degrees of separation from pure black. It’s very saturated and free of undertones and is a popular pick for doors and accent walls.
It’s very difficult to distinguish Wrought Iron and Iron Ore from each other with the naked eye, even when placed side by side. In my opinion, along with being just a touch darker, Iron Ore is a tiny bit warmer and richer than Wrought Iron.
