The 22-point LRV gap — 28 for Stonewashed Blue vs 6 for Iron Ore — means Stonewashed Blue will open up a space more effectively. Where Stonewashed Blue leans cool, Iron Ore reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 35.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Stonewashed Blue vs Iron Ore in Real Spaces
8 real rooms side by side. Seeing Stonewashed Blue 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. Stonewashed Blue 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. Stonewashed Blue 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. Stonewashed Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Stonewashed Blue will make the room feel meaningfully brighter than Iron Ore would.
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. Stonewashed Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Stonewashed Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Stonewashed Blue will make the room feel meaningfully brighter than Iron Ore would.
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. Stonewashed Blue reflects noticeably more light off the walls, making the space read more open than Iron Ore.

Digital color is approximate.
