St Giles Blue vs Pewter Green in Real Spaces
5 real rooms side by side. Seeing St Giles Blue and Pewter Green 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. St Giles Blue reflects noticeably more light off the walls, making the space read more open than Pewter Green.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. St Giles Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. St Giles Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. St Giles Blue reflects noticeably more light off the walls, making the space read more open than Pewter Green.
