Atrium White vs Iron Ore
Atrium White is a PPG color while Iron Ore comes from Sherwin-Williams. Atrium White reads as beige-white, while Iron Ore reads as grey — two distinct hue families, not close cousins. At LRV 85 vs 6, Atrium White will read as the brighter of the two — a 79-point gap that matters most in north-facing or low-light rooms. At ΔE 65.8, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Atrium White vs Iron Ore in Real Spaces
10 real rooms side by side. Seeing Atrium White 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Atrium White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Atrium White will make the room feel meaningfully brighter than Iron Ore would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Atrium White will make the room feel meaningfully brighter than Iron Ore would.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Atrium White reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Atrium White will make the room feel meaningfully brighter than Iron Ore would.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The LRV gap is large enough that Atrium White will make the room feel meaningfully brighter than Iron Ore would.
Mudroom
A mudroom color needs to hold up under the most casual scrutiny: a glance as you're coming and going, often in mixed or artificial light. Atrium White reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Patio
Patio colors are seen under changing outdoor light throughout the day — morning, midday, and golden hour each reveal different qualities. Atrium White reflects noticeably more light off the walls, making the space read more open than Iron Ore.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Atrium White will make the room feel meaningfully brighter than Iron Ore would.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Atrium White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
