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

5 simulated room previews — drag the slider on each to see Treron on one side and Flagstone on the other.
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.
