Great Falls vs Iron Ore
Both from Sherwin-Williams's palette. Hue-wise, Great Falls belongs to the blue family and Iron Ore to the grey family. Great Falls (LRV 15) reflects noticeably more light than Iron Ore (LRV 6), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Great Falls runs cool while Iron Ore is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 30.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Great Falls vs Iron Ore in Real Spaces
10 real rooms side by side. Seeing Great Falls 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Great Falls will make the room feel meaningfully brighter than Iron Ore would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Great Falls reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Great Falls reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Great Falls returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Great Falls reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. Great Falls reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. Great Falls returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Patio
Outside, paint color competes with sky, landscaping, and direct sun — all of which shift how both of these read compared to an indoor chip. Great Falls returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Great Falls reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The LRV gap is large enough that Great Falls will make the room feel meaningfully brighter than Iron Ore would.

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.
