Matrix vs Iron Ore
Where Matrix belongs to Jotun's range, Iron Ore is a Sherwin-Williams color. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Matrix (LRV 20) reflects noticeably more light than Iron Ore (LRV 6), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 22.9, 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 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Matrix vs Iron Ore in Real Spaces
7 real rooms side by side. Seeing Matrix 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 Matrix 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. Matrix 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. Matrix 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. Matrix 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. Matrix 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. Matrix reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Matrix reflects noticeably more light off the walls, making the space read more open than Iron Ore.

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.
