Cathedral Gray vs Denim Drift in Real Spaces
3 real rooms side by side. Seeing Cathedral Gray and Denim Drift 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 Cathedral Gray will make the room feel meaningfully brighter than Denim Drift would.
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. Cathedral Gray 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. Cathedral Gray reflects noticeably more light off the walls, making the space read more open than Denim Drift.
