Rock Slide vs Iron Ore in Real Spaces
10 real rooms side by side. Seeing Rock Slide 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 Rock Slide 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. Rock Slide 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. Rock Slide 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. Rock Slide 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. Rock Slide reflects noticeably more light off the walls, making the space read more open than Iron Ore.
Home Office
