Steel Curtain vs Rosemary in Real Spaces
8 real rooms side by side. Seeing Steel Curtain and Rosemary 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 Steel Curtain will make the room feel meaningfully brighter than Rosemary 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. Steel Curtain reflects noticeably more light off the walls, making the space read more open than Rosemary.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Steel Curtain reflects noticeably more light off the walls, making the space read more open than Rosemary.
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. Steel Curtain 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. Steel Curtain reflects noticeably more light off the walls, making the space read more open than Rosemary.
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. Steel Curtain reflects noticeably more light off the walls, making the space read more open than Rosemary.
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. Steel Curtain reflects noticeably more light off the walls, making the space read more open than Rosemary.
