Cement grey vs Glass Bead in Real Spaces
5 real rooms side by side. Seeing Cement grey and Glass Bead 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 Glass Bead will make the room feel meaningfully brighter than Cement grey 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. Glass Bead reflects noticeably more light off the walls, making the space read more open than Cement grey.
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. Glass Bead reflects noticeably more light off the walls, making the space read more open than Cement grey.
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. Glass Bead reflects noticeably more light off the walls, making the space read more open than Cement grey.
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 Glass Bead will make the room feel meaningfully brighter than Cement grey would.
